Reaction Steps

N-[6-[2-(4-Cyano-phenyl)-2H-pyrazol-3-yl]-7-methyl-8-(3-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-2-dimethylamino-acetamide (Ex. 14, 10 mg, 0.018 mmol) was stirred in MeCN (0.5 mL) and a solution of MeBr (ca. 30% in MeCN, 0.01 mL) added, followed after 15 mins by a further MeBr solution (0.05 mL). The reaction mixture was stirred for 18 hrs before being concentrated in vacuo to give title compound as an off-white solid (11 mg).
