実験手順

A solution of tert-butyl 2-cyano-5,7-dihydro-6H-pyrrolo[3,4-d]pyrimidine-6-carboxylate (150 mg) in trifluoroacetic acid and dichloromethane (1:1, 1 mL) was stirred for one h and evaporated. The residue was purified by flash column chromatography (silica, 0-4% methanol containing 10% ammonium hydroxide in dichloromethane) to yield 6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidine-2-carbonitrile.
