Reaction Steps
A solution of 2-chloro-N-(4′-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1′-biphenyl-3-yl)isonicotinamide (50 mg, 0.12 mmol) in 3,5-dimethylpiperidine (1 ml) was heated at 120° C. for 18 h in a sealed tube. The reaction was concentrated under vacuum, the residue purified by preparative HPLC, to give, after evaporation of the solvents under vacuum N-(4′-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1′-biphenyl-3-yl)-2-(3,5-dimethylpiperidin-1-yl)isonicotinamide.
