Reaction Steps

A solution of 4-{[1-(2-chlorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl]oxy}-5-[(5-methylpyridin-2-yl)amino]-5-oxopentanoic acid (5.0 mg, 0.011 mmol), methylamine (0.021 ml (2M in THF), 0.043 mmol) and TBTU (7.0 mg, 0.021 mmol) in THF (1 mL) was stirred at ambient temperature for 5 hrs. Water (1 mL) was added and the reaction mixture was purified by preparative HPLC: Mobile phase A: 100% ACN, Mobile phase B: 5% ACN+95% 0.1M NH4OAc in water; Gradient: 0% A to 50% A over 45 min; Flow: 25 ml/min; UV: 235 nm, to give the title compound (3.0 mg). 1H NMR (500 MHz, CDCl3) δ 8.88 (br s, 1H), 8.57 (s, 1H), 8.39 (s, 1H), 8.11 (m, 2H), 7.62 (m, 1H), 7.51 (m, 4H), 5.91 (m, 1H), 5.63 (br s, 1H), 2.82 (d, 3H), 2.51 (m, 4H), 2.30 (s, 3H), HRMS: calcd for (M+H+) C23H2335ClN7O3: 480.1551. Found: 480.1503.
