To a solution of N-(2-tetrahydropyranyloxy)-2-[7-(5-(4-(5-oxazolyl)phenyl)-2-thienyl)-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (100 mg) in N,N-dimethylformamide (3 ml) was added triethylamine (57 mg) and cyclopropylaminocarbonyloxybenzene (40 mg) and the reaction mixture was heated at 50° C. for 4 hours. The mixture was added ethyl acetate and the solution was washed with successively water, a 5% aqueous citric acid-solution, a satuated aqueous sodium hydrogencarbonate and brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatography on silica gel 60 (2% methanol-chloroform) to give N-(2-tetrahydropyranyloxy)-2-[4-cyclopropylaminocarbonyl-7-(5-(4-(5-oxazolyl)phenyl)-2-thienyl)-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (65 mg) as a pale yellow powder.
