5-Methoxy-1,3-dimethyl-1H-pyrazole-4-carbaldehyde → N-(2-Aminophenyl)-4-{1-[(5-methoxy-1,3-dimethyl-1H-pyrazol-4-yl)methyl]piperidin-4-yl}benzamide

Participants

Reaction Steps

Using an analogous procedure to that described in Example 3, tert-butyl 2-[(4-piperidin-4-ylbenzoyl)amino]phenylcarbamate (prepared as described in Method 1 below; 200 mg, 0.51 mmol) was reacted with 5-methoxy-1,3-dimethyl-1H-pyrazole-4-carbaldehyde (92.6 mg, 0.60 mmol) to give the title compound (68 mg, 36%); NMR Spectrum: (DMSO d6) δ 1.63 (m, 2H), 1.78 (m, 2H), 2.00 (m, 2H), 2.06 (s, 3H), 2.57 (m, 1H), 2.94 (m, 2H), 3.25 (s, 2H), 3.50 (s, 3H), 3.99 (s, 3H), 4.86 (br s, 2H), 6.60 (m, 1H), 6.78 (d, 1H), 6.97 (m, 1H), 7.17 (d, 1H), 7.37 (d, 2H), 7.91 (d, 2H), 9.55 (s, 1H); Mass Spectrum: M+H+434.
