Dimethylcarbamoyl Chloride → 4-(6-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-1-carboxylic acid dimethylamide

Participants

Reaction Steps

To a mixture of 6-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-2-piperidin-4-yl-2,3-dihydro-isoindol-1-one (Example 1, 20 mg, 0.033 mmol) and triethylamine (23 uL, 0.165 mmol) in DMF (1.5 mL) is added dimethylcarbamyl chloride (11 mg, 0.1 mmol). The mixture is stirred at room temperature for 1 hour. The reaction is filtered and the filtrate is purified by mass-trigger preparative RP LC-MS to afford the title compound 4-(6-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-1-carboxylic acid dimethylamide (155) as a white solid: 1H NMR (400 MHz, MeOD-d4) δ 8.29 (s, 1H), 8.26 (br, 1H), 7.96 (dd, 1H), 7.93 (s, 1H), 7.72 (dd, 1H), 7.48 (dd, 1H), 7.35 (s, 1H), 4.50 (s, 2H), 4.35-4.29 (m, 1H), 3.83 (d, 2H), 3.38-3.30 (m, 2H), 3.02-2.95 (m, 3H), 2.88 (s, 6H), 1.88-1.84 (m, 3H), 1.36 (d, 6H), 1.25 (d, 6H); ESMS m/z 670.2 (M+H+).
