Procedure

Triethylamine (0.091 mL, 0.652 mmol) was added to a solution of 3-mesityl-2,5-dimesityl-7,8-dihydro-6H-pyrazolo[1,5-a]pyrrolo[3,2-e]pyrimidine (100 mg, 0.326 mmol) which was prepared in Example 71 in dichloromethane (4 mL), butyryl chloride (0.037 mL, 0.358 mmol) was added dropwise at room temperature, followed by stirring for two hours. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate, washed with brine, and then dried over MgSO4. The solvent was evaporated, and the residue was subjected to silica gel column chromatography (7 g), to give the title compound (52 mg, 42%) as a pale yellow oil from a fraction of ethyl acetate-hexane (1:4 v/v).
