Hydrochloric Acid → 3-[(1S)-2-Hydroxy-1-methylethoxy]-5-[(1-methyl-1H-indol-5-yl)oxy]-N-(1-methyl-1H-pyrazol-3-yl)benzamide

Participants

Reaction Steps

10% Hydrochloric acid (0.5 mL) was added to a solution of 3-((1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethoxy)-5-[(1-methyl-1H-indol-5-yl)oxy]-N-(1-methyl-1H-pyrazol-3-yl)benzamide (120 mg, 0.22 mmol) in methanol (5 mL). The reaction was stirred at ambient temperature for 1 hour, saturated sodium bicarbonate solution added and the methanol evaporated. The aqueous residue was taken to pH 2 and extracted with ethyl acetate. The extracts were combined, washed with brine, dried (MgSO4), filtered and evaporated in vacuo to give the crude product which was chromatographed on silica, eluting with 1% methanol in ethyl acetate, to give the desired product (85 mg).
