Reaction Steps

A solution of 259B (680 mg, 1.9 mmol) in CH2Cl2 (10 mL) was treated with TFA (1 mL) at room temperature. The reaction mixture was stirred for 16 hours, then concentrated. The residues was dissolved in EtOAc (20 mL) and washed with saturated aqueous NaHCO3 (2×20 mL), dried (Na2SO4), filtered and concentrated in vacuo to afford 170 mg of Compound 259C.
