実験手順: A solution of Ethyl 4-[aminomethyl]benzeneacetate (4.12 g) in anhydrous dichloromethane (60 ml) containing triethylamine (3.0 ml), was added over 20 min to a cold (-15°) stirred solution of acryloyl chloride (1.73 ml) in dry dichloromethane (50 ml) and stirring was continued for 0.75 h. After washing the dichloromethane solution with 8% aqueous sodium bicarbonate soln (2×50 ml) and drying (MgSO4), the organic solvent was removed by rotary evaporation to yield a a solid (approximately 6 g) which was triturated with cyclohexane to give the title compound as a solid (4.1 g) m.p. 93°-95°. was added over 20 min to a cold (-15°) After washing the dichloromethane solution with 8% aqueous sodium bicarbonate soln (2×50 ml) drying (MgSO4) the organic solvent was removed by rotary evaporation

実験手順: 1.3 g (4.5 mmol) of 6-(4-fluoro-3-methylbenzylcarbamoyl)pyrimidine-4-carboxylic acid and 1.042 g (5.4 mmol) of ethyl (4-aminomethylphenyl)acetate were dissolved in 30 ml of DMF, after which 1.02 g (4.9 mmol) of dicyclohexylcarbodiimide and 0.607 g (4.5 mmol) of hydroxybenzotriazole were added at 5° C. The mixture was stirred for 5 hours (h) and filtered with suction. The solvent was removed in vacuo and the residue was taken up in ethyl acetate; this solution was washed with a saturated aqueous solution of NaHCO3. The organic phase was dried (MgSO4), filtered and evaporated under reduced pressure. This resulted in 2.66 g of product, which was further purified by means of preparative HPLC. MS (ES+): m/e=464.19. filtered with suction The solvent was removed in vacuo this solution was washed with a saturated aqueous solution of NaHCO3 The organic phase was dried (MgSO4) filtered evaporated under reduced pressure

実験手順: 0.5 g (2.6 mmol) of ethyl (4-cyanophenyl)acetate was dissolved in 70 ml of ethanolic ammonia solution and hydrogenated, at room temperature and under standard pressure, over Raney nickel. After 45 minutes, the mixture was filtered and evaporated. This resulted in 0.42 g (82%) of ethyl (4-aminomethylphenyl)acetate. MS (ES+): m/e=194.11 the mixture was filtered evaporated This resulted in 0.42 g (82%) of ethyl (4-aminomethylphenyl)acetate
