Reaction Steps

A mixture of crude (S)—N6-(5-cyclopropyl-1H-pyrazol-3-yl)-N2-(1-(4-fluorophenyl)ethyl)pyridine-2,3,6-triamine (Method 9; 0.120 g, 0.34 mmol) and acetamidine hydrochloride (0.052 g, 0.55 mmol) in EtOH (5 ml) was heated at reflux overnight. After cooling to 25° C., saturated NaHCO3 solution (10 ml) and EtOAc (30 ml) were added to the reaction mixture. The organic layer was separated, washed with brine (10 ml), dried over Na2SO4, concentrated, and purified by chromatography (EtOAc:MeOH=100:1) to give the title compound as an off-white solid (0.055 g, 43%). NMR (400 MHz, d6-Acetone) 11.14 (br s, 1H), 8.44 (br s, 1H), 7.70 (d, J=8.4 Hz, 1H), 7.44 (m, 2H), 7.11 (m, 2H), 7.00 (br s, 1H), 6.00 (m, 2H), 2.12 (s, 3H), 2.11 (d, J=7.2 Hz, 3H), 0.89 (m, 2H), 0.65 (m, 2H). MS: Calcd.: 376. Found: [M+H]+ 377.
