[0001236] To a mixture of Example 2.160.3 (557.5 mg), 2-(2,5-dioxo-2,5-dihydro- lH-pyrrol-l- yl)acetic acid (272 mg) and 0-(7-azabenzotriazol-l-yl)-N,N,N’,N’-tetramethyluronium hexafluorophosphate (667 mg) inN N-dimethylformamide (1.75 mL) at 0 C was added Nu,Nu- diisopropylethylamine (0.459 mL). The resulting mixture was stirred at 0 C for 1 hour. The reaction mixture was mixed with saturated aqueous NH4C1 mixture, extracted with ethyl acetate and washed with brine. The organic layer was dried over sodium sulfate, filtered and concentrated. The residue was purified by silica gel column chromatography, eluting with petroleum ether/ ethyl acetate (2/1), to provide the title compound. MS (LC-MS) m/e 795.3 (M+Na) +., 25021-08-3
25021-08-3 2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid 319935, apyrrolines compound, is more and more widely used in various fields.
