Reaction Steps

A solution of 5-(cis-3,5-dimethyl-1-piperazinyl)-2-(methyloxy)aniline (D4) (587 mg, 2.5 mmol) in dichloromethane (4 ml) and pyridine (4 ml) was treated with a suspension of 6-chloro-3-pyridinesulfonyl chloride hydrochloride (D32) (700 mg, 3 mmol) in dichloromethane (4 ml). After stirring at room temperature for 15 minutes the mixture was evaporated and the residue co-evaporated with toluene (×2). The residue was then partitioned between dichloromethane and saturated aqueous sodium bicarbonate solution. The organic layer was separated, washed in water, brine, dried and evaporated. The residue was triturated with ether/and dried to give the title product. MS (ES+) 411/413 [M+H]+.
