Reaction Steps

(S)-1-{6-Amino-5-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-pyridin-3-yl}-ethane-1,2-diol was prepared as follow: To a solution of asymmetic dihydroxylation-mix α (2.33 g) in a 1:1 mixture of t-BuOH and water (8 mL each) cooled to 0° C. was added 3-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-5-vinyl-pyridin-2-ylamine (500 mg, 1.67 mmol). The reaction mixture was stirred at 0° C. until consumption of the starting material. Three more loadings of AD-mix α was added periodically to increase the reaction rate. Water was added (5 mL) and the mixture was extracted with EtOAc (3×20 mL). The combined organic layer was dried over Na2SO4, and concentrated. The crude product was purified by reverse phase HPLC to provide (S)-1-{6-amino-5-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-pyridin-3-yl}ethane-1,2-diol (320 mg, 53% yield).
