実験手順: Allyl 4-[({(2S,4R)-1-[(3-chloro-4-fluoro-1-methyl-1H-indol-5-yl)carbonyl]-4-[1-(methylsulfonyl)-4-piperidinyl]-2-pyrrolidinyl}carbonyl)amino]benzoate was prepared from the compound prepared in Example 63 following the procedures described in Example 5, 9 and 8. (Note: in the step corresponding to Example 5, allyl 4-aminobenzoate was used in place of tert-butyl 4-aminobenzoate. In the step corresponding to Example 8, the acid prepared in Example 92 was used in place of 1-(N,N′-bis(tert-butoxycarbonyl)carbamimidoyl)piperidine-4-carboxylic acid). After that, the crude allyl ester was treated with palladium(0) following the procedure described in Example 91 to give the title compound as an off-white solid.

実験手順: Allyl 4-[({(2S,4R)-1-{(2E)-3-[5-chloro-2-(1H-tetrazol-1-yl)phenyl]-2-propenoyl}-4-[1-(methylsulfonyl)-4-piperidinyl]-2-pyrrolidinyl}carbonyl)amino]benzoate was prepared by following the procedures described in Examples 5, 9 and 8 starting from the compound prepared in Example 63. (Note: in the step corresponding to Example 5, allyl 4-aminobenzoate was used in place of tert-butyl 4-aminobenzoate. In the step corresponding to Example 8, (2E)-3-[5-chloro-2-(1H-tetrazol-1-yl)phenyl]acrylic acid was used in place of 1-(N,N′-bis(tert-butoxycarbonyl)carbamimidoyl)piperidine-4-carboxylic acid). After that, to a solution of the crude allyl ester (48 mg) in N,N-dimethylformamide (1 mL) was added tetrakis(triphenylphosphine)palladium(0) (2 mg) and 1,3-dimethylbarbituric acid (4 mg) and the reaction stirred overnight at room temperature. Further tetrakis(triphenylphosphine)palladium(0) (3 mg) was added at this juncture and stirring continued at room temperature for 7 h. The reaction mixture was left to stand overnight, diluted with a 1:1 mixture of diisopropylether and dichloromethane (1 mL) and the resulting precipitate collected by filtration. The yellow powder obtained was washed with dichloromethane and dried to give the title compound having the following physical properties (25 mg). stirring continued at room temperature for 7 h The reaction mixture was left to stand overnight the resulting precipitate collected by filtration The yellow powder obtained was washed with dichloromethane dried

実験手順: 1.8 g (10 mmol) of allyl 4-aminobenzoate, 50 ml of THF and 1.7 ml (12 mmol) of triethylamine were introduced into a round-bottomed flask. A solution of 3.3 g (10 mmol) of α-methoxycarbonyl-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)acetic acid chloride in 25 ml of THP was added dropwise and the mixture was stirred at room temperature for 2 hours. The reaction medium was poured into water, and extracted with ethyl acetate. The organic phase was decanted off, dried over magnesium sulfate and evaporated. The residue obtained was recrystallized from ethanol; 3.3 g (69%) of the expected compound of melting point 155°-156° C. were recovered after filtration and drying. extracted with ethyl acetate The organic phase was decanted off dried over magnesium sulfate evaporated The residue obtained was recrystallized from ethanol 3.3 g (69%) of the expected compound of melting point 155°-156° C. were recovered after filtration drying
