Participants

Reaction Steps

To a solution of 4-[(methyloxy)methyl]-1-({[4-(methyloxy)phenyl]methyl}oxy)-2-nitrobenzene D118 (1.57 g, 5.18 mmol) in DCM (80 mL) was added trifluoroacetic acid (3.99 mL, 51.80 mmol). After 1 hr the mixture was washed with water (3×25 mL) and then extracted with 10% aq potassium carbonate solution (3×20 mL). The combined extracts were back washed with diethyl ether (20 mL) and then the pH was adjusted to 1 with 2N HCl, the mixture was extracted with DCM (3×25 mL), the combined extracts were washed with water (25 mL) and brine (25 mL), dried(MgSO4), filtered and concentrated in vacuo. The residue was purified by silica gel chromatography eluting with 5-40% EtOAc in isohexane to afford the title compound as a bright yellow oil. 0.72 g, 76%
