実験手順

The crude 5-bromo-3-(4-piperidinyl)-1H-indazole-7-carboxamide (Intermediate 6) (1.23 mmol) was suspended in dichloromethane (20 mL) and treated with triethyl amine (0.856 mL, 6.15 mmols), and ethane sulfonyl chloride (0.175 mL, 1.85 mmols) at 0° C. After 2 hrs, the mixture was concentrated to dryness in vacuo at ambient temperature, treated with water (25 mL), and extracted with dichloromethane (100 mL). The organic phase was washed with water, dried over MgSO4, filtered, and concentrated to give a light brown solid. This was purified by combiflash (column 10 g, eluting with 100% dichloromethane, 5% ethyl acetate/dichloromethane, 30% ethyl acetate/dichloromethane) to give the title compound (0.161 g, 32%).
