To a solution of [5-({[1-(4-Hydroxymethyl-benzyl)-1H-[1,2,3]triazole-4-carbonyl]-amino}-methyl)-4,6-dimethyl-pyridin-2-yl]-carbamic acid tert-butyl ester (690 mg, 1.331 mmol) in 10 mL of DCM was added dropwise a solution of thionyl chloride (0.107 mL, 1.464 mmol) and pyridine (1.615 μL, 0.02 mmol) in 10 mL of DCM. The reaction mixture was stirred for 3 h at 40° C. and saturated aqueous bicarbonate solution was added. The layers were separated and the aqueous layer was extracted with DCM. The combined organic solution was dried over MgSO4, filtered and concentrated under vacuum to yield the crude product which was used in the next step without further purification. LCMS (Method A) RtA=1.681; [M+H]+=485.0.
