実験手順

A solution of 1 mmole of 1-carbomethoxy-9-chloro-7-phenylpyrimido[1,2-a][1,4]benzodiazepin-3(5H)-one in tetrahydrofuran was reacted at room temperature with the stoichiometric amount of lithium aluminum hydride and stirred for several hours. It was decomposed with water and 15% sodium hydroxide and worked up to give 1-hydroxymethyl-9-chloro-7-phenylpyrimido[1,2-a][1,4]benzodiazepin-3(5H)-one.
