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 cyclohexylamine (1 ml) was heated at 110° C. for 36 h and then at 160° C. for 48 h in a sealed tube. The reaction was concentrated under vacuum, the residue triturated with water and purified by preparative HPLC. The solvent was evaporated under vacuum to give 2-cyclohexylamino)-N-(4′-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1′-biphenyl-3-yl)isonicotinamide (14.4 mg).
