Pyridine → Benzophenone oxime

참여 물질

반응 단계

A solution of benzophenone (10.0 g), hydroxylamine hydrochloride (10.0 g), pyridine (50 ml), and absolute ethanol (50 ml) was pumped through the CMR (15 ml/min; 155°-60° C., 700 kPa). The effluent was cooled and the solvent removed by rotary evaporation, and the residue stirred with cold water (50 ml). The crued oxime was filtered off and recrystallised from ethanol to afford pure product (8.0 g; 73% yield), m.p. 140.5°-141° C., cf lit.5 for a batchwise preparation by microwave heating.
