Procedure
Prepared from 3-(3-indolyl)acrolein and 1 equivalent of 2-amino-4,5,7,8-tetrahydro-6H- thiazolo[5,4-d]azepine by reductive amination with 0.9 equivalents of sodium cyanoborohydride. Purification of the crude product by column chromatography is carried out using neutral aluminium oxide of activity stage I (toluene/ethyl acetate/ethanol=4:1:0.5). Yield: 11% of theory, Melting point: 155°-160° C.
