Participants

Reaction Steps

To a solution of the intermediate from step B (8.4 g, 30.18 mmol) in THF (150 mL) was added methanol (15 mL), Na(CN)BH3 (5.7 g, 90.54 mmol) and AcOH (30 mL). The resulting solution was stirred at room temperature for 48 hours. The reaction was concentrated in vacuo. To the residue was added 1 M Na2CO3 solution (800 mL) and extracted with ether (3×). The organic layer was dried over anhydrous Na2SO4 filtered and concentrated in vacuo to give the desired product as a white solid. 1H NMR (CDCl3, 500 MHz): 8.04 (d, J=8.2 Hz, 2H), 7.46 (d, J=8.2 Hz, 2H), 4.08 (s, 2H), 3.94 (s, 3H), 1.49 (s,9H). LC-MS=2.43; (M+H−56)=224.9.
