The base was released with dichloromethane/sodium hydroxide solution from (14), which was prepared as in Example 13, and after drying the solution the dichloromethane was removed by distillation. Hydrochloride (17) was obtained, under the conditions given in Example 2, from the base thus obtained, in a yield of 86% theoretical and with a melting point of 214° C.
