Reaction Steps

The mixture of (R)-4-(6-(cis-4-phenyl-cyclohexyloxy)-5-trifluoromethylnaphthalen-2-yl)-4-methyloxazolidin-2-one (46.7 mg, 0.0000995 mol) and lithium hydroxide (26 mg, 0.0011 mol) in ethanol (2 mL, 0.04 mol) and water (0.4 mL, 0.02 mol) was heated to reflux overnight. LCMS showed reaction complete. The solvent was removed under vacuum and the residue was partitioned between water and CH2Cl2. The aqueous layer was extensively extracted with CH2Cl2. The combined organic phase was dried over Na2SO4. The concentrated residue was taken up into DCM and subjected to chromatographic purification with CH2Cl2/MeOH (10:90 to 80:20) to give the product as a white solid (22.1 mg, 50% yield). LCMS 427.26 ([M−NH2]+, 100%). 1H NMR (400 MHz, CD3OD) δ ppm 1.52 (s, 3H), 1.67 (brd, J=11.8 Hz, 2H), 1.82 (dd, J=13.4, 13.1 Hz, 2H), 2.02 (ddd, J=13.1, 12.8, 3.0 Hz, 2H), 2.20 (d, J=14.8 Hz, 2H), 2.65 (ddd, J=12.2, 12.2, 3.8 Hz, 1H), 3.68 (d, J=10.9 Hz, 1H), 3.73 (d, J=10.9 Hz, 1H), 5.01 (brs, 1H), 7.14-7.30 (m, 5H), 7.50 (d, J=9.3 Hz, 1H), 7.71 (dd, J=9.3, 2.2 Hz, 1H), 7.95 (d, J=2.1 Hz, 1H), 8.08 (d, J=9.3 Hz, 1H), 8.16 (d, J=9.3 Hz, 1H).
