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-methylpiperidine (1 ml) was heated at 120° C. for 18 h in a sealed tube. The reaction was concentrated under vacuum, the residue chromatographed on an SPE (C18) eluting with a water/acetonitrile gradient, to give, after evaporation of the solvents under vacuum N-(4′-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1′-biphenyl-3-yl)-2-(3-methylpiperidin-1-yl)isonicotinamide (16 mg).
