Reaction Conditions

Reaction Steps

A mixture of the pyrazole (390 mg, 1.37 mmol) of Example 3 and chloroethylamine hydrochloride (238 mg, 2.05 mmol) was stirred and heated at 150° C. for 24 hours. After cooling, the mixture was partitioned between saturated aqueous sodium bicarbonate solution (100 ml) and dichloromethane (2×50 ml). The combined organic layers were washed with brine (30 ml), dried over magnesium sulphate, filtered and concentrated under reduced pressure. The resulting brown oil was purified by flash chromatography on silica gel eluting with dichloromethane:methanol (90:10, by volume) to afford the title compound (244 mg) as a brown oil.
