Potassium Carbonate → 5-[3-[4-(4-Fluorophenyl)piperazin-1-yl]propyl]-2-methyl-2,3,4,5-tetrahydropyrrolo[2,3-e][1,2]thiazin-4-one 1,1-dioxide

Participants

Reaction Steps

A suspension of 200 mg (1 mmol) of Compound 12, 385 mg (1.5 mmol) of 1-(3-chloropropyl)-4-(4-fluorophenyl) piperazine and 207 mg (1.5 mmol) of potassium carbonate in 15 ml of 2-butanone was refluxed for 24 hours. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by chromatography on a silica gel column (eluent:chloroform), whereby 335 mg of the title compound were obtained yield: (80%).
