Participants

Reaction Steps

A solution of (S)-3-(aminomethyl)-N6-(5-cyclopropyl-1H-pyrazol-3-yl)-5-fluoro-N2-(1-(4-fluorophenyl)ethyl)pyridine-2,6-diamine (Example 3, 0.16 g, 0.42 mmol), 2-morpholinoacetic acid (0.06 g, 0.42 mmol), HBTU (0.16 g, 0.42 mmol) and DIEA (0.16 g, 1.2 mmol) in DCM (3 ml) was stirred at room temperature for 1 hour. The reaction was then quenched with a saturated aqueous solution of NaHCO3, and extracted with DCM (2×50 ml). The combined organic fractions were dried over Na2SO4, filtered, and then concentrated. The resulting oil was purified by column chromatography (DCM-MeOH=100:1) to give the title compound (0.02 g, 10%). 1H NMR (400 MHz, CD3OD) δ 7.35 (br s, 2H), 7.17 (br s, 1H), 7.01-6.97 (m, 2H), 6.06 (br s, 1H), 5.16-4.99 (m, 1H), 4.30 (br s, 2H), 3.68 (br s, 4H), 3.06 (br s, 2H), 2.48 (br s, 4H), 1.87-1.82 (m, 1H), 1.51 (d, J=6.4 Hz, 3H), 0.91 (br s, 2H), 0.64 (br s, 2H). MS: Calcd.: 511. Found: [M+H]+ 512.
