Ammonia → 1-Amino-7-isoquinolinol

참여 물질

반응 단계

Boron tribromide (35 mL) in 50 mL of dichloromethane was added dropwise to a stirred solution of 7-methoxy-isoquinoline-1ylamine (21.6 g) in 70 mL of dichloromethane at 10° C. After stirring for 4 d at ambient temperature the reaction mixture was poured on ice and the pH adjusted to pH 9 by adding concentrated aqueous ammonia. The precipitated material was collected by filtration and dried in vacuo to give 19.3 g (97%) of the title compound as a light brownish solid. M.p. 260° C. (decomp.); El-MS: 160 (M+).
