Procedure

A solution of 8-(1-ethylpropyl)-3-mesityl-2,5-dimethyl-7,8-dihydro-6H-pyrazolo[1,5-a]pyrrolo[3,2-e]pyrimidine (468 mg, 1,24 mmol) in N-methyl-2-pyrrolidinone (10 mL) was heated at 200° C. for 15 hours. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate, washed with brine, and then dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was subjected to silica gel column cromatography (10% ethyl acetate/hexane), to give the title compound (168 mg, 36%) as pale yellow crystals.
