Reaction Steps

Bromine (1.0 M solution in carbon tetrachloride 0.3 mL, 0.30 mmol) was added to a solution of 3-benzo[b]furan-2-yl-8-(1-ethylpropyl)-2,5-dimethyl-7,8-dihydro-6H-pyrazolo[1,5-a]pyrrolo[3,2-e]pyrimidine (50 mg, 0.13 mmol) in N,N-dimethylformamide (0.3 mL) at 0° C., followed by stirring for one hour. Hypo water was added thereto, and the mixture was diluted with ethyl acetate, washed with an aqueous saturated solution of ammonium chloride and brine, dried over anhydrous magnesium sulfate and evaporated. The residue was purified by silica gel column chromatography (10% ethyl acetate/hexane), to give the title compound (57 mg) as white crystals.
