Water → Methyl {[5'-isopropyl-2'-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate

Participants

Reaction Steps

To a solution of 1-[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methanamine (166 mg, 0.51 mmol) and methyl chloroformate (107 μL, 1.39 mmol) in CH2Cl2 (5 mL) was added N,N-diisopropylethylamine (485 μL, 2.79 mmol). The reaction was stirred at room temperature for twenty minutes and then was poured into H2O (50 mL). The mixture was extracted with EtOAc (100 mL), and the organic layer was washed with brine (50 mL), dried over Na2SO4, filtered, and concentrated. Purification by flash chromatography with 2% to 20% EtOAc/hexanes afforded methyl {[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate. Rf=0.29 (15% EtOAc/hexanes). LCMS=382.3 (M+1)+. 1H NMR (CDCl3, 500 MHz) δ 7.68 (s, 1H), 7.57 (d, J=8.0 Hz, 1H), 7.31 (d, J=8.0 Hz, 1H), 7.25 (dd, J=8.5, 2.5 Hz, 1H), 6.97 (d, J=2.5 Hz, 1H), 6.91 (d, J=8.5 Hz, 1H), 4.17 (m, 2H), 3.75 (s, 3H), 3.65 (s, 3H), 2.89 (m, 1H), 1.25 (d, J=7.0 Hz, 6H).
