Participants

Reaction Steps

The representative procedure for amide formation was used in the reaction of methyl 2-[4-amino-3-(4-{[(2,3-dichlorophenyl)sulfonyl]amino}-3-fluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]acetate (0.035 g, 0.067 mmol) with N,N-dimethylethanolamine (1 mL). Purification by preparative HPLC (25 to 100% acetonitrile in 0.1 M aqueous ammonium acetate over 20 min at 21 mL/min using an 8μ Hypersil HS C18, 250×21 mm column, Rt 7.50-8.07 min) afforded 2-(dimethylamino)ethyl 2-[4-amino-3-(4-{[(2,3-dichlorophenyl)sulfonyl]amino}-3-fluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]acetate as an off-white solid (0.008 g, 0.014 mmol): 1H NMR (DMSO-d6, 400 MHz) δ 8.24 (s, 1H), 7.96 (d, 1H), 7.83 (d, 1H), 7.48 (t, 1H), 7.32 (m, 3H), 5.23 (s, 2H), 4.29 (t, 2H), 2.86 (m, 2H), 2.39 (s, 6H); MS: (M−H)− 580.
