Reaction Steps

Combine 2-{2-[5-fluoro-2-(2-[1,2,3]triazol-1-yl-ethylamino)-pyrimidin-4-yl]-benzo[b]thiophen-7-yl}-benzaldehyde (800 mg, 1.8 mmol), cyanoborohydride (silica supported, 1 mmol/g, 2.7 g, 2.7 mmol), trimethylacetic acid (0.55 g, 4.7 mmol), and mono-methylamine (0.42 g, 5.4 mmol) in 12 mL of dioxane. Heat the reaction mixture at 100° C. for 20 min in microwave reactor. Cool it to RT. Dilute with chloroform/IPA (3:1, v/v), 50 mL. Wash with water, aqueous saturated sodium chloride, and dry over magnesium sulfate. Remove the organic solvent. Purify the residue by column chromatography [chloroform/methanol/ammonium hydroxide (35% in water), 7/3/0.05] to give the title compound (425 mg, 38%). MS (ES) m/z 460 [M+1]+.
