With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.221352-46-1,2-(tert-Butoxycarbonyl)isoindoline-1-carboxylic acid,as a common compound, the synthetic route is as follows.
To a solution of 2,3-dihydro-isoindole-1,2-dicarboxylic acid 2-tert-butyl ester (344 mg, CAS 221352-46-1), 1-(4-amino-3-fluoro-phenyl)-1H-pyridin-2-one (265 mg; CAS 536747-52-1) and DIPEA (0.34 ml) in 10 ml acetonitrile and 1 ml DMF was added BOP-Cl (382 mg). The reaction mixture was stirred for 24 hrs at rt, diluted with AcOEt and washed with 1M HCl, 1M NaOH and brine. The organic layers were dried over magnesium sulfate, evaporated and purified by chromatography (silica gel; AcOEt) to deliver the title compound as a yellow oil (280 mg). MS: 450.4 (M+H)+., 221352-46-1
The synthetic route of 221352-46-1 has been constantly updated, and we look forward to future research findings.
