Procedure

50 gm of 50% hydrobromic acid were slowly added dropwise to 19 gm of the product obtained in step (a), while stirring. The vessel containing the resulting mixture was then connected to a Vigreux-column, and the mixture was heated until a temperature of about 124° C. was reached. After three hours of heating at that temperature, about 35 ml of liquid were distilled off. The residue solidified upon cooling and was purified by washing with acetone, yielding 22 gm of the desired product which had a melting point of 148° C.
