Reaction Steps

An aqueous solution of sodium hydroxyde (2M, 270 □l), was added at room temperature to a solution of N-[4-(1,3-benzodioxol-5-yl)-3-methoxy-1-methyl-1H-pyrazol-5-yl]-4-chloro-N-[(4-chlorophenyl)sulfonyl]benzenesulfonamide (Preparation 43) (32 mg) in a mixture of methanol (1 ml) and dichloromethane (1 ml). After 1 h, an aqueous saturated solution of ammonium chloride (4 ml) and water (4 ml) were added and the mixture was extracted with dichloromethane (3×5 ml). The combined organic fractions were dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by preparative TLC (silica) eluted with dichloromethane:methanol (95:5) to yield the title compound as colourless oil (15.1 mg).
