YieldReaction ConditionsOperation in experiment
With N-ethyl-N,N-diisopropylamine In dimethyl sulfoxide at 80℃; for 16h; 295 Example 295: 3-[l-[2-(5-Carbamoylisoindolin-2-yl)-6-methyl-4-oxo-chromen-8- (1534) A mixture of 6-chloro-3-[l-(2-ethylsulfmyl-6-methyl-4-oxo-chromen-8-yl)ethylamino]pyridine- 2-carboxylic acid (150 mg, 344.9 mmol, 1 eq), isoindoline-5-carboxamide (102.8 mg, 517.37 umol, 1.5 eq, HC1), and DIEA (222.9 mg, 1.7 mmol, 300 uL, 5 eq) in DMSO (1 mL) was stirred at 80°C for 16 hours to give a dark suspension. The mixture was poured into water (20 mL) and EtOAc (20 mL) was added. The aqueous phase was adjusted pH to 2 with HC1 (aq 1M), and then the solid crude product was collected by filtration. The crude product was treated with DMF (3 mL) and aqueous ammonia (0.25 mL), and the mixture was purified by reverse phase HPLC (C- 18 column, Water -acetonitrile gradient with 0.2% ammonium hydroxide) to give 3-[l-[2-(5- carbamoylisoindolin-2-yl)-6-methyl-4-oxo-chromen-8-yl]ethylamino]-6-chloro-pyridine-2- carboxylic acid. MS ES+ m/z 519 [M+H]+.
