Procedure
Catalytic hydrogenation of the 4-methylimino derivative obtained in step (e) in ethanol containing excess methylamine, in the presence of platinum oxide, proceeds slowly at 50° C. under ordinary pressure. After the theoretical amount of hydrogen has been taken up, the solution is filtered, evaporated, and the residue is distilled: B.p.0.4 =86°-88° C.; Yield; 80%.
