Benzenepropanoyl chloride → N1-{4-[4-amino-1-[1-(1-methylpiperidin-4-yl)piperidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-3-phenylpropanamide

Reaction Steps

3-Phenylpropanoyl chloride (77 mg, 0.458 mmol) was added to a solution of 3-(4-amino-3-methoxyphenyl)-1-[1-(1-methylpiperidin-4-yl)-piperidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (100 mg, 0.229 mmol) in pyridine (1.2 mL). After 5 hours, the solvent was evaporated and the residue was purified by flash column chromatography to give N1-{4-[4-amino-1-[1-(1-methylpiperidin-4-yl)piperidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-3-phenylpropanamide (24 mg, 18%). 1H NMR (CDCl3-d) δ 1.70 (m, 2H), 1.85 (m, 2H), 2.04 (m, 4H), 2.30 (s, 3H), 2.41 (m, 5H), 2.75 (m, 2H), 2.97 (m, 2H), 3.08 (m, 4H), 3.90 (s, 3H), 4.75 (m, 1H), 5.71 (bs, 2H), 7.24 (m, 8H), 7.76 (s, 1H), 8.34 (s, 1H), 8.52 (d, J=8.12, 1H).
