Reaction Steps

To a solution of 1.4 (0.0532 g, 0.136 mmol) in THF/MeOH (2/1) (1.5 mL) was added LiOH (0.50 mL, 0.500 mmol). The resulting mixture was stirred overnight at 23° C., quenched with excess 1N HCl, and extracted with EtOAc. The combined organic layers were dried over Na2SO4 and concentrated. The crude residue was purified by combiflash (0 to 40% EtOAc/hexane) to afford 1 (0.0426 g, 83.1% yield). MS ESI (neg.) m/e: 375.1 (M−H)+. 1H NMR (400 MHz, CDCl3) δ ppm 7.32-7.39 (3H, m), 7.24-7.31 (2H, m), 6.85-6.95 (6H, m), 5.08 (2H, s), 3.87 (3H, s), 2.99 (2H, t, J=7.8 Hz), 2.73 (2H, t, J=7.8 Hz), 2.34 (3H, s).
