실험 절차

Prepared from 3-(4-isoquinolinyl)acrolein and 2-amino-4,5,7,8-tetrahydro-6H-thiazolo[5,4-d]azepine by reductive amination with sodium cyanoborohydride (in methanol in the presence of I equivalent of glacial acetic acid). The crude product is purified by column chromatography on silica gel (acetone/methanol/conc. ammonia =50:12:0.5). At first the title compound (A) is eluted. Yield: 4% of theory, Melting point: 205°-208° C. (ether).
