Reaction Steps

A mixture of (S)-2-cyclohexylmethyl-succinic acid 1-methyl ester (60.0 g, 263 mmol) and tetrahydrofuran (600 mL) was stirred at room temperature and then cooled to −5° C. over 30 min. To the reaction mixture was added 1.0 M borane in tetrahydrofuran (520 mL) dropwise over 45 min, keeping the internal temperature below 0° C. To the reaction mixture was added MeOH (100 mL) dropwise to quench the reaction. The reaction mixture was concentrated to about 100 mL by rotary evaporation. (Trifluoromethyl)benzene (200 mL) was added and volume was reduced to 25 mL by rotary evaporation. (Trifluoromethyl)benzene (100 mL) was added to the resulting thick oil and the volume was reduced to ˜25 mL to provide crude title product (56.3 g).
