To a mixture 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 chloroform (1 ml) was added a solution of isopropyl isocyanate (18 mg) in chloroform (1 ml) at 0° C. under nitrogen atmosphere. After being stirred for 1 hour, the mixture was concentrated in vacuo. The residue was dissolved in ethyl acetate and the solution was washed with water, a saturated aqueous sodium bicarbonate solution and brine, dried over magnesium sulfate, and evaporated in vacuo. The residue was purified by preparative thin-layer chromatography (chloroform-methanol=10-1, v/v) to give N-(2-tetrahydropyranyloxy)-2-[4-isopropylcarbamoyl-7-(5-(4-(5-oxazolyl)phenyl)-2-thienyl)-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (92 mg) as a pale yellow powder.
