Reaction Steps

A solution of 41 (0.36 g, 1.1 mmol) in TFA (5 mL) and CH2Cl2 (5 mL) was stirred at room temperature for 40 minutes. The mixture was concentrated in vacuo and the residue was dissolved in EtOAc (50 mL). Upon sequential washings with 1 N NaOH (2×50 mL) and brine (50 mL), the organic solution was dried (Na2SO4) and concentrated to afford 42 (0.20 g, 77%).
