Hydrogen Peroxide → HCID 19881086, compound

Participants

Reaction Steps

To a solution of 2.0 g of 7-acetyl-2,3-dihydro-4-[4-(4-(2-pyrimidinyl)-1-piperazinyl)butyl]thieno[3,2-f]-1,4-thiazepin-5(4H)-one in 20 ml of acetic acid was added to 1.0 g of 30% hydrogen peroxide and the mixture was stirred for 20 hours at room temperature. Then, the mixture was poured into ca. 3% aqueous sodium hydrogen sulfite solution and extracted with chloroform. The extract was washed with water, dried over magnesium sulfate and the solvent was distilled off. The resulting crude crystals were recrystallized from ethanol to give 1.5 g of 7-acetyl-2,3-dihydro-4-[4-(4-(2-pyrimidinyl)-1-piperazinyl)butyl]thieno[3,2-f]-1,4-thiazepin-5(4H)-one 1-oxide as white crystals, melting at 103°-106° C.
