Reaction Steps

To a solution of N-(2-tetrahydropyranyloxy)-2-[7-(5-(3-aminophenyl)-2-thienyl)-4-benzoyl-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (150 mg) in dichloromethane (3 ml) was added ethyl isocyanate (22 mg) at 0° C. and the reaction mixture was stirred at ambient temperature for 5 hours. The mixture was poured into water and was extracted with ethyl acetate. The organic layer was washed with water, saturated 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 (3% methanol-chloroform) to give N-(2-tetrahydropyranyloxy)-2-[4-benzoyl-7-(5-(3-(ethylaminocarbonylamino)phenyl)-2-thienyl)-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (75 mg) as a white powder.
