Procedure
1 g (2.7 millimoles) of the benzyl alcohol derivative from Example 27 was dissolved in 5 ml of pyridine, and 1 ml of acetic anhydride was added. The mixture was stirred overnight at room temperature, after which ice/water was added and the resulting solid was filtered off under suction, washed with water, with 0.5N HCl and again with water and dried to give 1 g of the title compound of melting point 73°-74° C.
