Acetyl chloride → N-[6-[2-(4-Cyano-phenyl)-4-methyl-2H-pyrazol-3-yl]-7-methyl-8-(3-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-acetamide

Participants

Reaction Steps

The title compound was prepared from N-[7-methyl-6-propionyl-8-(3-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-acetamide (Int. 26, 11 mg, 0.023 mmol) and 4-hydrazino-benzonitrile (7 μL, 0.051 mmol) using similar methods to those employed in Example 40, Steps 3 and 4. During step 4 the acetyl group was lost, which was re-introduced by reaction with acetyl chloride using a similar method to that used for Intermediate 18 to give the title compound as a cream solid (3 mg).
