Procedure

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 3.5 ml tetrahydrofurane were added at 0–4° C. 0.37 ml N-ethyldiisopropylamine and 0.19 mg 2-methyl-isonicotinoyl chloride hydrochloride. 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 ethylacetate/methanol 9:1 to yield 0.025 g (50%) [2-(4-methoxy-7-morpholin-4-yl-benzothiazol-2-yl)-4,5,7,8-tetrahydro-1H-imidazo[4,5-d]azepin-6-yl]-(2-methyl-pyridin-4-yl)-methanone as yellow solid; MS (ISP): m/e=505 (M+H+).
