Reaction Conditions

Reaction Steps

A mixture of 3-(2-chloro-4-pyrimidinyl)-2-(4-fluorophenyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine (i.e. the product of Step B) (200 mg, 0.54 mmol) and isopropylamine (5.0 mL) was stirred at 34° C. for 18 h. The reaction mixture was diluted with dichloromethane (50 mL) and treated with silica gel (20.0 g). The silica gel suspension was concentrated under reduced pressure to leave a mixture of silica gel and crude product, which was purified by silica gel chromatography using a gradient of ethyl acetate/hexanes (1:9 to 1:0) as eluant to give 115 mg of the title product, a compound of the present invention, as an off-white solid.
