Under room temperature, a 1M borane THF solution (48 mL) was added to an R-CBS 1M toluene solution (120 mL). 1-(3-Bromo-2-methyloxyphenyl)heptane-1-one (7, 13 g) was added, and the mixture was stirred for 1 hour. Methanol was added, a solvent was distilled off, and the residue was purified by chromatography to obtain (S)-1-(3-bromo-2-methyloxyphenyl)heptane-1-ol (8, 12.86 g, yield 75%).
