Participants

Reaction Steps

An aqueous solution of sodium hydroxyde (1M, 0.91 ml) was added at room temperature to a solution of N-(4-(1,3-benzodioxol-5-yl)-3-{2-[(5-chloro-2-pyrimidinyl)oxy]ethoxy}-1-methyl-1H-pyrazol-5-yl)-N-(methylsulfonyl)methane sulfonamide (Preparation 49) (50 mg) in a mixture of methanol (1 ml) and dichloromethane (0.3 ml). After 1 h the reaction was diluted with an aqueous saturated solution of ammonium chloride (4 ml) 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 pale yellow oil was purified by preparative TLC (silica) eluted with dichloromethane:methanol (95:5) to yield the title compound as a colourless oil (33 mg)
