Reaction Steps

In a sealed vial were added consecutively (R)-2-chloro-N-(1-(4-(4-chlorophenyl)piperidin-1-yl)-3-methyl-1-oxobutan-2-yl)acetamide (31.4 mg, 0.085 mmol), pyrazole (11.5 mg, 0.17 mmol), K2CO3 (35.2 mg, 0.26 mmol) and acetonitrile (0.4 mL). The reaction mixture was then heated at 75° C. for 36 h, cooled to rt., and the solids were filtered. The filtrate was concentrated and purified by preparative HPLC to provide Example 290, (R)—N-(1-(4-(4-chlorophenyl)piperidin-1-yl)-3-methyl-1-oxobutan-2-yl)-2-(1H-pyrazol-1-yl)acetamide (32 mg, 94% yield) as a white solid. MS found: 403.3 (M+H).
