The base was released with dichloromethane/sodium hydroxide solution from (5), which was prepared according to Example 5, and after drying the solution dichloromethane was removed by distillation. Hydrochloride (6), which had a melting point of 80° C., was obtained in a yield of 73% theoretical from the base obtained, under the conditions given in Example 2.
