반응 단계

Mix 6-(2,3,4,5-tetrahydro-1H-benzo[c]azepin-7-yloxy)nicotinamide (Example 447, Part E, 0.300 g, 1.06 mmol), K2CO3 (0.366 g, 2.65 mmol), and (3-chloropropyl)cyclohexane (0.179 g, 1.11 mmol) in DMF (5.3 mL). Heat at 50° C. overnight, then increase the temperature to 80° C. for 3.5 hours. Cool the reaction mixture to room temperature and add ethyl acetate (100 mL). Wash with water (1×30 mL), brine (1×30 mL), dry the organic layer over Na2SO4, filter and concentrate. Purify by flash chromatography eluting with 6% to 15% (2.0 M NH3 in methanol) in ethyl acetate to give the title compound: MS ES+ 408.3 (M+H)+, HRMS calcd for C25H34N3O2 408.2651 (M+H)+, found 408.2652, time 0.46 min; HPLC [YMC-Pro pack C-18 (150×4.6 mm, S-5 microm), 0.05% TFA/acetonitrile in 0.05% TFA/water at 1.0 mL/min, 10-20% over 5 min, 20-95% over 18 min], tR=13.3 min, 100% purity.
