Reaction Steps

To a solution of commercially available 4-(3-amino-1H-indazol-5-yl)-6-(2-isobutoxyphenyl)pyrimidin-2(1H)-one (60 mg, 0.15 mmol) in dimethylacetamide (4 mL) and diisopropylethylamine (130 pt, 0.76 mmol, 5 eq) was added propionic acid (56 μL, 0.76 mmol, 5 eq) followed by HATU (290 mg, 0.76 mmol, 5 eq). The reaction mixture was stirred at room temperature for 16 h. Formation of product was confirmed by LC/MS and the product was purified by preparatory HPLC (reverse-phase, acetonitrile/water with 0.1% formic acid) to yield 17 mg (26%) of the title compound: 1H-NMR (400 MHz, d6-DMSO): δ 11.85 (s, 1H), 8.79 (s, 1H), 8.28-8.35 (m, 1H), 7.64 (s, 1H), 7.49-7.58 (m, 1H), 7.20 (d, 1H), 7.08-7.13 (m, 1H), 6.63 (s, 2H), 4.07-4.14 (m, 1H), 3.83-3.91 (m, 2H), 3.15-3.19 (m, 1H), 2.93-3.03 (m, 2H), 1.95-2.08 (m, 1H), 1.14-1.21 (m, 3H), 0.90-0.96 (m, 6H). MS (EI) for C24H25N5O3: 431 (MH+).
