실험 절차

A thick suspension of the product of stage (b) (3.68 g) in conc. hydrochloric acid (50 ml) was stirred at -5° whilst a solution of sodium nitrite (0.9 g) in water (10 ml) was added dropwise so that temperature did not exceed 0°. Stirring was continued for 30 min. The resulting suspension was filtered to remove starting material and the filtrate added in a few portions to a solution of stannous chloride dihydrate (13.5 g) in hydrochloric acid (15 ml) at -20° and warmed to ambient temperature. The solid that separated was filtered off and recrystallised from hot methanol (100 ml) to give the title compound as white plates (0.39 g) m.p. 192°-193°. The mother liquors afforded a second crop (0.52 g).
