Reaction Steps
To a solution of 5-chloro-7-morpholin-4-yl-2-phenyl-pyrazolo[1,5-a]pyrimidine (150 mg, 0.48 mM) in 1,4-dioxane (5.0 mL), there was added hydrazine monohydrate (0.23 mL, 4.8 mM) and the mixture was stirred at 90° C. for 14 hours. The reaction mixture was cooled down to room temperature, then water was added thereto and the mixture was extracted with ethyl acetate. The organic phase thus obtained was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to thus give the title compound (133 mg, yield: 90%). MS (ESI) m/z (M+H)+ 311
