A solution of Intermediate 36 (196 g) and trimethylsilyl azide (283 ml, Tokyo Kasei Kogyo) in dimethylformamide (667 ml) was added with cesium fluoride (305 g, Wako Pure Chemical Industries) with stirring and stirred at 70° C. for 4 days. The reaction mixture was cooled to room temperature and then added twice with water in a volume of 2.75 l in total. This reaction mixture was stirred with ice cooling for 2 hours, and the deposited precipitates were collected by filtration. Then, the precipitates were washed with water to obtain a roughly purified product of the title compound (142 g).
