Reaction Steps

(R)-4-(6-(trans-4-(1,1-difluoroethyl)cyclohexyloxy)-5-(trifluoromethyl)naphthalen-2-yl)-4-methyloxazolidin-2-one (530 mg, 1.16 mmol) was dissolved in EtOH (5 mL). Then LiOH (835 mg, 34.8 mmol, 30.0 eq.) in 2 mL water was added to the mixture. The mixture was heated to 80° C. and stirred for 15 h. Solvent was removed. DCM was added and filtrated. The filtrate was concentrated and purified by silica gel chromatography using DCM/methanol (10/1) to give the title compound (200 mg, 40%) as a slight yellow solid. EDI-MS (M-NH2): 415.2. HPLC: 99.36%. 1H NMR (400 MHz, CD3OD) δ 8.13 (t, 1H), 8.02 (d, 1H), 7.86 (s, 1H), 7.58 (dd, 1H), 7.48 (d, 1H), 4.45-4.41 (m, 1H), 3.85-3.72 (m, 2H), 2.14-2012 (m, 2H), 1.89-1.86 (m, 2H), 1.74-1.68 (m, 4H), 1.51-1.32 (m, 7H).
