Participants

Reaction Steps

A solution of 2-[2-(2,5-dimethyl-2H-pyrazol-3-ylamino)-5-isopropenyl-pyridin-4-ylamino]-N-methyl-benzamide (0.13 g, 0.345 mmole, 1 eq) in ethanol (10 mL) was degassed with N2 and to this PtO2 (0.012 g, 0.052 mmole, 0.15 eq) was added. The resulting mixture was stirred at room temperature under H2 atmosphere with balloon pressure for 10 h. After completion of the reaction, it was filtered through a celite bed which was then washed with ethanol (10 mL). The filtrate was evaporated under reduced pressure to give a solid residue which was purified by washing with diethyl ether to give the title compound as a gray solid (80 mg, 61%). 1H-NMR (400 MHz, DMSO-d6): δ 1.24-1.26 (d, 6H, J=6.76 Hz), 2.05 (s, 3H), 2.75-2.76 (d, 3H, J=4.48 Hz), 2.89-3.10 (m, 1H), 3.53 (s, 3H), 5.96 (s, 1H), 6.67 (s, 1H), 6.85-7.10 (m, 1H), 7.40-7.50 (m, 2H), 7.65-7.67 (d, 1H, J=7.76 Hz), 7.86 (s, 1H), 8.36 (s, 1H), 8.60-8.70 (brs, 1H), 9.89 (s, 1H). LC-MS [M+H]+=379.2.
