Procedure

A mixture of the product from step (b) (2.4 g), hydantoin (Aldrich, 0.98 g) and ammonium acetate (0.74 g) in glac. acetic acid (2.4 ml) was heated at 120° C. for 4 hours. The mixture was cooled and the resulting precipitate filtered off and dried to give the desired product as a yellow solid (2.4 g).
