Participants

Reaction Steps

To a suspension of 0.04 g 2-(4-methoxy-7-morpholin-4-yl-benzothiazol-2-yl)-1,4,5,6,7,8-hexahydro-imidazo[4,5-d]azepine hydrochloride in 3.4 ml tetrahydrofurane were added at 0–4° C. 0.07 ml N-ethyldiisopropylamine and 0.012 g cyclopropanecarbonyl chloride. The mixture was refluxed for 17 hours, silicagel was added and the solvent was distilled off. The residue was transferred to a column prefilled with silicagel and was chromatographed with dichloromethane/methanol 96:4 to yield 0.04 g (90%) cyclopropyl-[2-(4-methoxy-7-morpholin-4-yl-benzothiazol-2-yl)-4,5,7,8-tetrahydro-1H-imidazo[4,5-d]azepin-6-yl]-methanone as yellow solid; MS (ISP): m/e=454 (M+H+).
