Procedure

0.011 mol of the compound obtained in Step F is dissolved in 100 ml of 95° alcohol and introduced into a 400 ml autoclave; 0.5 g of Raney nickel is then added. The solution is saturated with ammonia gas, and hydrogen is introduced until a pressure of 50 bars is obtained. The reaction mixture is stirred for 5 hours at 60° C. and is then cooled, filtered and evaporated under reduced pressure. The oil obtained is dissolved in anhydrous ethyl ether and a solution of ethyl ether saturated with gaseous hydrogen chloride is added dropwise. The precipitate formed is filtered off under suction and recrystallised.
