Reaction Steps

2-(4-Bromophenyl)-2-methylpropan-1-ol (500 mg, 2.182 mmol) was dissolved in Dichloromethane (7.2 mL) in a 20 mL vial. Diethylaminosulfur trifluoride (0.433 mL, 3.27 mmol) was then slowly added To a solution and the resultant mixture was stirred at ambient temperature overnight. At which time, an additional 0.5 eq of DAST was added and stirred for an additional 4 hours. The reaction mixture was purified directly by MPLC on silica gel (eluting with 5% ethyl acetate in hexanes) to afford the title compound. 1H NMR (500 MHz, CDCl3) δ 7.43-7.42 (d, 2H), 7.10-7.09 (d, 2H), 2.88 (s, 1H), 2.83 (s, 1H), 1.35 (s, 3H), 1.30 (s, 3H).
