Potassium Hydroxide → HCID 121482660, compound

Participants

Reaction Steps

To a solution of Intermediate 6 (530 mg) in a solution of potassium hydroxide (182 mg) in water (9 mL) was added a solution of hydroxylamine-O-sulfonic acid (183 mg, 2 eq) in a solution of potassium hydroxide (273 mg) in water (18 mL) and the resulting mixture was stirred at room temperature for 30 min under nitrogen. The mixture was diluted with ethyl acetate and washed with brine. The organic extract was concentrated and subjected to silica gel column chromatography (0 to 30% ethyl acetate in heptane) to yield 150 mg of Intermediate 7 as a mixture of diastereomers.
