Sodium Hydroxide → HCID 67352569, compound

Participants

Reaction Steps

A mixture of compound 8 (460 mg, 0.899 mmol) and NaOH 6N (1350 μl, 11.10 mmol) in THF (20 ml) and water (10 ml) is stirred at RT for 3 days. Water is added and the organic solvent is evaporated. The basic aqueous solution (pH 12) is washed with AcOEt. The aqueous phase is then treated with HCl 6N until pH 6 when a solid precipitated. The solid is recovered by filtration and the aqueous phase is extracted with AcOEt, washed with brine, dried over Na2SO4 and then evaporated. The two fractions of obtained solid are combined and triturated with AcOEt (containing 2% MeOH) to give the title compound (150 mg, 0.301 mmol, 33.5% yield).
