Reaction Steps

To a degassed mixture of 2-(4-bromophenyl)-5-cyclopropyl-6-[(3-hydroxypropyl)(methylsulfonyl)amino]-N-methyl-2H-indazole-3-carboxamide (10 mg, 0.019 mmol), cyclopropylboronic acid (5 mg, 0.058 mmol), potassium phosphate (17 mg, 0.080 mmol) in toluene (0.5 mL) and water (50 μL) were added tricyclohexylphosphine (1 mg, 0.0038 mmol) and Pd(OAc)2 (0.4 mg, 0.0019 mmol) and the reaction was heated at 100° C. for 2 h. The mixture was concentrated to dryness and purified by preparative LCMS (5-40-100% ACN in 0.1 aqueous formic acid) to afford Compound (53) as a white solid (2.5 mg, 27%). ESI-MS m/z calculated for [M+H]+: 483.2; found: 483.2; 1H NMR (400 MHz, MeOD) δ 7.85 (s, 1H), 7.58-7.43 (m, 2H), 7.39 (s, 1H), 7.28 (d, J=8.5 Hz, 2H), 4.06-3.81 (m, 2H), 3.76-3.57 (m, 2H), 3.17 (s, 3H), 2.94 (s, 3H), 2.54-2.34 (m, 1H), 2.19-1.96 (m, 1H), 1.96-1.68 (m, 2H), 1.21-0.94 (m, 5H), 0.85-0.76 (m, 2H), 0.75-0.59 (m, 1H).
