実験手順
1 g of 7-chloro-1-(β-chloroethyl)-2-chloromethyl-5-(2-furyl)-2,3-dihydro-1H-1,4-benzodiazepine in 40 ml of methanol is left to react with 0.8 g of methylamine at 50° C. for 3 hours. The reaction mixture is then worked up as described in Example 7. On purification by chromatography, the fractions containing the more highly polar title compound are separated off. 0.4 g of 1,2,3,4,4a,5-hexahydro-9-chloro-3-methyl-7-(2-furyl)-pyrazino[1,2-a][1,4]benzodiazepine is obtained therefrom.
