“…Upon completion, the reaction was diluted with diethyl ether (25 mL) and washed with water (10 mL) and brine (10 mL). The organic layer was dried with MgSO 4 , concentrated under vacuum, and purified by flash chromatography (5:1 hexanes:ethyl acetate eluent) to yield phenol 23 (62 mg, 42% yield over two steps): R f = 0.26 (3:1 hexanes:ethyl acetate); 1 H NMR (500 MHz, CDCl 3 ) δ 7.48-7.32 (m, 10H), 6.29 (t, J = 2.1 Hz, 1H), 6.13 (d, J = 2.1 Hz, 2H), 5.17 (s, 1H), 5.00 (s, 4H); 13 …”
