Procedure

8.4 g. of 4-chloro-1ethyl-10,11-dihydrobenzo [4,5]cyclohepta [1,2-b ]pyrazolo [4,3-e ]pyridin-5(1H)one (0.027 mol.) dissolved in 90 ml. of an alcoholic methylamine solution (270 g/1) are allowed to stand at room temperature for five hours. After this time, 7.1 g. of precipitated 1-ethyl-10,11-dihydro-4-(methylamino)benzo [4,5]cyclohepta [1,2-b ]pyrazolo-[4,3-e ]pyridin-5(1H)one are collected, m.p. 148°-150°. A sample recrystallized from absolute ethanol melts at 149°-150°.
