Reaction Steps

To a solution of ethyl 2-(tert-butoxycarbonyl)-3-hydroxy-3-(4-(trifluoromethyl)phenyl)propanoate (9.25 g, 24.5 mmol) in DMF (3.78 mL, 49.0 mmol) and 1,2-dichloroethane (20 mL) was added tetra-n-butylammonium iodide (9.51 g, 25.7 mmol), chloromethyl methyl ether (5.59 mL, 73.5 mmol) and N,N-diisopropylethylamine (12.8 mL, 73.5 mmol). The mixture was gradually heated to 45° C. and stirred overnight. The crude product was concentrated in vacuo, diluted with CH2Cl2 and washed three times with water. The organic phase was dried over Na2SO4 and concentrated in vacuo. The crude product was purified by silica gel chromatography: 16%-20%-25% EtOAc-Hexane. The product was obtained as a white solid. LCMS (API-ES) m/z (%): 322 (M+1-100).
