To a solution of N-(2-tetrahydropyranyloxy)-2-[7-(5-(4-chlorophenyl)-2-thienyl)-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (100 mg) and triethylamine (22.3 mg) in acetonitrile (2 ml) was added N-(2-methoxyethylaminosulfonyloxy)succinimide (55.6 mg) and the mixture was stirred at ambient temperature for 1 hour. The mixture was partitioned with ethyl acetate and water. The organic layer was separated, washed with 5% citric acid solution, water, saturated sodium bicarbonate solution and brine, dried over magnesium sulfate, and evaporated in vacuo. The residue was purified by silica gel column chromatography eluting with a mixture of chloroform and methanol (200:1, 100:1, 200:3) to give N-(2-tetrahydropyranyloxy)-2-[(S)-7-(5-(4-chlorophenyl)-2-thienyl)-4-(2-methoxyethylaminosulfonyl)-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (80.0 mg) as a colorless amorphous powder.
