(Diethylamino)sulfur trifluoride → HCID 86730298, compound

Participants

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. DAST (0.433 mL, 3.27 mmol) was then slowly added to the solution. Stirred at ambient temperature overnight. TLC showed presence of starting material. Another 0.5 eq. of DAST was added and stirred for 4 hours. TLC then showed consumption of starting material. The reaction was loaded directly on a silica column and the column was then dried out. Purified with a Teledyne Isco Combiflash Rf purification system using a gradient of 5% EtOAc/hexanes. Isolated 1-bromo-4-(1-fluoro-2-methylpropan-2-yl)benzene as a clear liquid. 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).
