Piperidine → 4-[1-(2-aminopyrimidin-4-yl)-3-methyl-1H-indazol-6-yl]-2-(1,3-oxazol-4-yl)but-3-yn-2-ol

Participants

Reaction Steps

To a vial was added 4-(6-iodo-3-methylindazol-1-yl)pyrimidin-2-amine (150 mg, 0.43 mmol), piperidine (1.5 mL), tetrakis(triphenylphosphine)palladium (49.36 mg, 0.04 mmol), copper(I) iodide (8.14 mg, 0.04 mmol) and 2-(1,3-oxazol-4-yl)but-3-yn-2-ol (87.87 mg, 0.64 mmol). The mixture was stirred at RT for 20 mins. Reaction mixture was concentrated in vacuo. DCM (5 mL) added and mixture was concentrated in vacuo. This was repeated twice. The crude material was purified by column chromatography (Biotage, 98:2 to 88:12 DCM: methanol gradient). Further purification by flash column chromatography gave the title compound: 1H (500 MHz, DMSO) delta 1.81 (3H, s), 2.58 (3H, s), 6.26 (1H, s), 6.99 (2H, s), 7.04 (1H, d, J=5.5 Hz), 7.39 (1H, dd, J=8.2, 1.1 Hz), 7.85 (1H, d, J=8.1 Hz), 8.13 (1H, s), 8.26 (1H, d, J=5.5 Hz), 8.36 (1H, s), 8.87 (1H, s); LC-MS: m/z=+361.05 (M+H)+.
