実験手順: To a 60% dispersion of NaH in mineral oil (25 mg, 0.625 mmol) in DMA (4 mL) was added N,N-diethylethanolamine (24 mg, 0.205 mmol). The reaction was stirred at room temperature for 20 minutes. A solution of 3-[(4-{[6-(bromomethyl)pyridin-2-yl]methoxy}benzoyl)amino]-N-cyclopropyl-4-methylbenzamide (77 mg, 0.155 mmol) in DMA (2 mL) was added dropwise to the reaction which was then stirred for 1 h at room temperature. The reaction was quenched by the addition of water (1 mL) and was purified by preparative HPLC to give the title compound as a white solid (29 mg, 35%); NMR Spectrum: (DMSOd6) 0.58 (m, 2H), 0.69 (m, 2H), 0.96 (t, 6H), 2.26 (s, 3H), 2.50 (m, 4H), 2.64 (t, 2H), 2.86 (m, 1H), 3.59 (t, 2H), 4.59 (s, 2H), 5.75 (s, 2H), 7.18 (d, 2H), 7.33 (d, 1H), 7.42 (m, 2H), 7.64 (dd, 1H), 7.80 (s, 1H), 7.87 (t, 1H), 7.96 (d, 2H), 8.36 (d, 1H), 9.83 (s, 1H); Mass Spectrum: M+H+ 531. was then stirred for 1 h at room temperature The reaction was quenched by the addition of water (1 mL) was purified by preparative HPLC

実験手順: To a stirred solution of 2-diethylamino-ethanol (0.42 mmol, 50 mg) in THF at room temperature was added NaH (0.85 mmol, 20 mg). Stirring continued for 10 min then 4-(4-benzyloxy-phenyl)-3-butyl-6-chloro-pyridazine (Example 1, 0.14 mmol, 50 mg) was added. The resulting mixture was stirred at 50-55° C. overnight. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with water, brine, dried (Na2SO4), filtered and concentrated under reduced pressure. The product was purified by column chromatography using 10% methanolic solution of ammonia (2.0 M ammonia in methanol) in ethyl acetate to provide {2-[5-(4-benzyloxy-phenyl)-6-butyl-pyridazin-3-yloxy]-ethyl}-diethyl-amine. The resulting mixture was stirred at 50-55° C. overnight extracted with ethyl acetate The organic layer was washed with water, brine dried (Na2SO4) filtered concentrated under reduced pressure The product was purified by column chromatography
