Sodium Hydroxide → HCID 68775846, compound

Participants

Reaction Steps

Sodium hydroxide (53 mg, 1.32 mmol) was added to a mixture of Example 256 (300 mg, 0.66 mmol) in THF (10 mL) and water (10 mL) and the reaction mixture was stirred at room temperature for 3 h. The THF was removed in vacuo and the aqueous phase was diluted with water (10 mL), washed with EtOAc (20 mL) and acidified to pH 2 with 2M aqueous HCl. The aqueous phase was extracted with EtOAc (50 mL) and the organic phase was dried (magnesium sulfate) and the solvent was removed in vacuo to give the title compound (204 mg, 72%) as a yellow solid. δH (CDCl3) 9.04 (1H, br s), 7.77-7.74 (1H, m), 7.59-7.47 (2H, m), 7.28-7.25 (1H, m), 3.72-3.66 (4H, m), 3.04-2.98 (4H, m), 2.51 (2H, s), 2.47 (2H, s), 1.06 (6H, s). LCMS (ES+) 429.0 (M+H)+.
