実験手順
6-[1-(4-chlorophenyl)-cyclopentylmethyl]-9-hydroxy-2-methyl-3,4-dihydro-2H-pyrazino[1,2-c]pyrimidine-1,8-dione (32-02) (296 mg, 66.3%) was synthesized from 9-benzyloxy-6-[1-(4-chlorophenyl)cyclopentylmethyl]-2-methyl-3,4-dihydro-2H-pyrazino[1,2-c]pyrimidine-1,8-dione (31-02) (500 mg, 1.151 mmol) as an off-white solid following the procedure as described for 6-biphenyl-2-ylmethyl-9-hydroxy-2-methyl-3,4-dihydro-2H-pyrazino[1,2-c]pyrimidine-1,8-dione (12-01).
