Reaction Steps

To a solution of 3.4 g of 4-(4-chlorobutyl)-2,3-dihydrothieno[3,2-f]-1,4-thiazepin-5(4H)-one in 100 ml of formic acid was added 2.9 ml of 30% hydrogen peroxide and the mixture was stirred for 3 hours at room temperature. Then, the mixture was poured into ca. 3% sodium hydrogensulfite solution and extracted with chloroform. The extract was washed with water, dried over magnesium sulfate and the solvent was distilled off to give 3.5 g of 4-(4-chlorobutyl)-2,3-dihydrothieno-[3,2-f]1,4-thiazepin-5(4H)-one 1,1-dioxide as a pale yellow oil.
