Reaction Steps

(R)-4-(6-(trans-4-(1,1-difluoroethyl)cyclohexyloxy)naphthalen-2-yl)-4-methyloxazolidin-2-one (865 mg, 2.22 mmol) and NIS (550 mg, 2.45 mmol, 1.1 eq.) were dissolved in CH3CN (5 mL). Then CF3COOH (76 mg, 0.67 mmol, 0.3 eq.) was added to the mixture dropwise at 0° C. The mixture was warmed to 15° C. and stirred for another 1 h. Then the mixture was extracted with EtOAc and the organic layer was concentrated and purified by silica gel chromatography using PE/EA (1/1) as eluent to give the title compound as a slight red solid (1.02 g, 90%). EDI-MS (M+1): δ 15.8. 1H NMR (400 MHz, CDCl3) δ 8.16 (d, 1H), 7.73 (d, 2H), 7.48 (dd, 1H), 7.18 (d, 1H), 6.49 (s, 1H), 4.45-4.40 (m, 2H), 4.33-4.30 (m, 1H), 2.27-2.25 (m, 2H), 2.03-2.01 (m, 2H), 1.84 (s, 3H), 1.65-1.24 (m, 8H).
