실험 절차

A mixture of ethyl trans-7-chloro-5-(4-hydroxy-2-methoxyphenyl)-1-neopentyl-2-oxo-1,2,3,5-tetrahydro-4,1-benzoxazepine-3-acetate (0.25 g), ethyl iodide (0.06 ml), potassium carbonate (0.15 g) and N,N-dimethylformamide (200 ml) was stirred for 3 h. The mixture was diluted with water (50 ml) and extracted with ethyl acetate (100 ml). The extract was washed with 1N hydrochloric acid and aqueous sodium bicarbonate, dried over magnesium sulfate and concentrated in vacuo to give ethyl trans-7-chloro-5-(4-ethoxy-2-methoxyphenyl)-1-neopentyl-2-oxo-1,2,3,5-tetrahydro-4,1-benzoxazepine-3-acetate (0.24 g) as colorless crystals (mp=164°-166° C.).
