Reaction Steps

A mixture of [5-({[1-(4-Chloromethyl-benzyl)-1H-[1,2,3]triazole-4-carbonyl]-amino}-methyl)-4,6-dimethyl-pyridin-2-yl]-carbamic acid tert-butyl ester (200 mg, 0.412 mmol), 3-methylpyrazole (33.9 mg, 0.412 mmol) and cesium carbonate (269 mg, 0.825 mmol) in 2 mL of DMF was stirred at 80° C. for 2 h. The reaction mixture was filtered and concentrated under reduced pressure. The residue was purified by preparative HPLC (Waters SunFire Prep C18 OBD 5 μm 30×100 mm, Flow 40 mL/min, ACN/water (0.1% TFA) 5/95 over 2 min, then ACN/water (0.1% TFA) 5195-100/0 over 15 min). LCMS (Method A) RtA=1.527; [M+H]+=531.1.
