Ethanethiol (47.6 mg, 0.76 mmol) and 25% aq. potassium hydroxide (172 mg, 0.77 mmol) were added to a solution of (R)-1-(3-methoxy-4-(oxiran-2-ylmethoxy)phenyl)-4-(4-(trifluoromethyl)phenyl)pyridin-2(1H)-one (32 mg, 0.08 mmol) Part A in THF (1.5 mL). The mixture was stirred overnight at RT. Diluted with EtOAc, washed with sat. NaHCO3, dried (Na2SO4), and concentrated. The residue was purified using ISCO flash chromatography (silica gel/hexanes/ethyl acetate 100:0 to 0:100 gradient) to afford the desired product (S)-1-(4-(3-(ethylthio)-2-hydroxypropoxy)-3-methoxyphenyl)-4-(4-(trifluoromethyl)phenyl)pyridin-2(1H)-one 15B (28 mg, 0.06 mmol, 76% yield) as a light yellow solid. LC/MS 480 (M+H)+, tR 0.97 min (method 5).
