Trifluoroacetic acid → HCID 11694142, compound

Participants

Reaction Steps

A solution of 5-(trifluoromethoxy)salicylaldehyde (4.85 mmol, 1.0 g), tert-butyl carbamate (14.55 mmol, 1.70 g), triethylsilane (14.55 mmol, 2.3 mL), trifluoroacetic acid (9.7 mmol, 0.72 mL) in acetonitrile was stirred at room temperature overnight. The reaction was quenched with saturated NaHCO3 and extracted with EtOAc. The combined organic layers were dried over Na2SO4 and purified by silica gel chromatography (15%-100% EtOAc/hexane). The resulting yellow solid was then dissolved in a mixture of TFA (10 mL) and dichloromethane (20 mL) and stirred for 2 hours at room temperature. The volatile solvents were then removed by rotovap to afford 2-(aminomethyl)-4-(trifluoromethoxy)phenol as a yellow oil. 1H NMR (CD3OD) 7.28 (s, 1H), 7.22 (m, 1H), 6.97 (m, 1H), 4.13 (s, 2H), 1.59 (s, 1H).
