Procedure

29 ml of phosphoryl chloride were added to 2.74 g (6.221 mmol) of the compound from Example 77A, and the mixture was stirred at RT overnight. The reaction mixture was then taken up in 430 ml of acetonitrile and, with ice cooling, stirred into 260 ml of concentrated ammonia solution (33% in water). The mixture was stirred at room temperature overnight and then concentrated on a rotary evaporator. The residue was stirred with water and ethyl acetate and the aqueous phase was extracted twice with ethyl acetate. The combined organic phases were washed with saturated aqueous sodium chloride solution and then dried over sodium sulphate, filtered and concentrated on a rotary evaporator. The residue was stirred with ethyl acetate and diethyl ether. A solid was filtered off with suction and then washed with diethyl ether and ethyl acetate. Drying under high vacuum gave 2.13 g of the title compound in a purity of 94% (79% of theory).
