(+)-Styrene oxide → (R)-methyl 2-chloro-4-(2-hydroxy-2-phenylethylthio)benzoate

Participants

Reaction Steps

150 mg of (R)-styrene oxide was reacted with methyl 2-chloro-4-mercaptobenzoate via Procedure S to afford (R)-methyl 2-chloro-4-(2-hydroxy-2-phenylethylthio)benzoate. 190 mg of (R)-methyl-2-chloro-4-(2-hydroxy-2-phenylethylthio)benzoate was hydrolyzed via Procedure M to give (R)-2-chloro-4-(2-hydroxy-2-phenylethylthio)benzoic acid. 170 mg of (R)-2-chloro-4-(2-hydroxy-2-phenylethylthio)benzoic acid was reacted via Procedure R to give (R)-2-chloro-4-(2-hydroxy-2-phenylethylsulfonyl)benzoic acid. 60 mg of 4-chloro-3-(pyridine-2-yl)aniline was coupled to (R)-2-chloro-4-(2-hydroxy-2-phenylethylsulfonyl)benzoic acid via Procedure G. The product was purified on reverse phase HPLC to yield (R)-2-chloro-N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(2-hydroxy-2-phenylethylsulfonyl)benzamide. MS (Q1) 527.2 (M)+.
