Procedure

A mixture of (tert-butyl-dimethyl-silanyloxy)-acetaldehyde (177.7 mg, 1.02 mmol), acetic acid (0.051 mL, 0.85 mmol) and N-[2-(2-amino-pyridine-4-carbonyl)-5-chloro-pyridin-3-yl]-4-methyl-3-trifluoromethyl-benzenesulfonamide (400 mg, 0.85 mmol) in DCM (3 mL) was stirred at RT for 1 hour. To the mixture was added sodium triacetoxyborohydride (360.8 mg, 1.7 mmol), stirred overnight. The mixture was extracted with ethyl acetate, washed with water, dried and concentrated. The residue was purified by flash column to afford N-[2-({2-[2-(tert-butyl-dimethyl-silanyloxy)-ethylamino]-pyridin-4-yl}-hydroxy-methyl)-5-chloro-pyridin-3-yl]-4-methyl-3-trifluoromethyl-benzenesulfonamide.
