A mixture of 1-(4-hydroxymethyl-benzyl)-1H-[1,2,3]triazole-4-carboxylic acid (0.95 g, 4.07 mmol), (5-Aminomethyl-4,6-dimethyl-pyridin-2-yl)-carbamic acid tert-butyl ester (1.024 g, 4.07 mmol), HATU (2.013 g, 5.30 mmol) and DIPEA (2.85 mL, 16.29 mmol) in 50 mL DMF was stirred at room temperature for 3 h. The reaction mixture was concentrated under reduced pressure. The residue was taken up in ethyl acetate and washed with 1 n HCl solution and saturated sodium bicarbonate solution. The organic solution was dried over MgSO4, filtered and concentrated to yield the crude product which was used in the next step without further purification. LCMS (Method A) RtA=1.279; [M+H]+=467.0.
