Reaction Steps

A mixture of N-(2-tetrahydropyranyloxy)-2-[7-(5-bromo-2-thienyl)-4-methanesulfonyl-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (200 mg), 4-methoxyphenylboronic acid (83.6 mg) and tetrakis(triphenylphosphine)palladium(0) (21.2 mg) in a mixture of 1,2-dimethoxyethane (2 ml) and aqueous 2M sodium carbonate (0.75 ml) was stirred for 2 hours at 80° C. After cooling to room temperature, the mixture was diluted with ethyl acetate, washed with aqueous saturated sodium bicarbonate and brine, dried over sodium sulfate and concentrated in vacuo. The obtained residue was purified with silica gel column chromatography (eluent; 0.5-3% methanol in chloroform) to give N-(2-tetrahydropyranyloxy)-2-[7-(5-(4-methoxyphenyl)-2-thienyl)-4-methanesulfonyl-1,1-dioxoperhydro-1,4-thiazepin-7-yl]acetamide (130 mg) as an amorphous powder.
