実験手順
To a solution of 4-amino-3-ethoxy-N-ethylbenzamide (0.53 g) obtained in Example 131c) in 0.2N hydrochloric acid (12.5 ml) was added 1M aqueous sodium nitrite solution (2.5 ml) under ice-cooling, and the mixture was stirred for 2 hr. To the obtained reaction mixture was added an aqueous solution (5 ml) of sodium azide (0.17 g) under ice-cooling, and the mixture was stirred for 30 min. The reaction mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to give the title compound as a yellow oil (0.50 g, 85%).
