実験手順

A mixture, under argon, of 0.560 g of product from Example 337, 2 ml of N,N-dimethylformamide and 0.250 g of sodium azide is stirred at 75° C. for 12 hours. The reaction mixture is diluted with diethyl ether, washed with water and saturated sodium chloride, dried and concentrated in vacuo to give 0.238 g of the desired product.

後処理
