実験手順

A mixture of 3.45 g (10 mmol) of ethyl (S)-8-chloro-11,12,13,13a-tetrahydro-9-oxo-9H-imidazo[1,5-a]pyrrolo[2,1-c][1,4]benzodiazepine-1-carboxylate, 100 mg of powdered potassium cyanide and 10 g (100 mmol) of tetrahydro-2H-pyran-4-ol is heated at 140° for 20 hours, whereupon the excess tetrahydro-2H-pyran-4-ol is distilled off and the residue is taken up in chloroform. The solution is washed with water, dried over magnesium sulphate and evaporated. By crystallization from ethyl acetate there is obtained tetrahydro-2H pyran-4-yl (S)-8-chloro-11,12,13,13a-tetrahydro-9-oxo-9H-imidazo[1,5-a]pyrrolo[2,1-c][1,4]benzodiazepine-1-carboxylate of melting point 226°-227°.
