Participants

Reaction Steps

A solution of compound 315 (165 mg, 0.31 mmol) in a mixture DCM-trifluoroacetic acid (3 mL, 2:1 ratio) was stirred at room temperature for 1.5 h; diluted with DCM and washed with a solution of KOH (830 mg, 15 mmol) in brine (15 mL), then brine, dried over MgSO4, filtered and concentrated. Purification by flash column chromatography (elution with 5% to 10% MeOH in DCM) gave title compound 316 (87 mg, 0.20 mmol, 64% yield) as a pale yellow solid.
