Application of 102359-00-2, These common heterocyclic compound, 102359-00-2, name is 2-Oxoindoline-5-carboxylic Acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a solution of 2-oxoindoline-5-carboxylic acid (0.200 g, 1.12 mmol), 1- [3- (dimethylamino) propyl] -3-ethylcarbodiimide hydrochloride (0.477 g, 2.47 mmol), diisopropylethylamine (0.586 mL, 3.37 mmol) and catalytic amount of N, N- dimethylaminopyridine in N, N-DIMETHYLFORMAMIDE/ACTEONITRILE (1: 1,4 mL) was added 2- methoxybenzylamine (0.295 mL, 2.26 mmol) and the reaction mixture stirred at room temperature for 1 h. The solvent was evaporated and the crude material was purified on a short silica gel column using dichloromethane containing 5% methanol as the eluent. This was followed by triturating from ethyl acetate to give 0.10 g (33% yield) of the yellow title compound : 1H NMR (DMSO-d6,400 MHz) 8 10.60 (br s, 1 H), 8.65 (t, J = 6 Hz, 1 H), 7.79-7. 77 (m, 2 1-1), 7.21 (t, J = 8 Hz, 1 H), 7.15 (d, 7= 8 HZ, 1 H), 6. 98 (d, J = 8 Hz, 1 H), 6.90-6. 84 (m, 2 H), 4.42 (d, J = 6 Hz, 2 H), 3.81 (s, 3 H), 3.53 (s, 2 H) ; MS (ES) m/z 297 (M++1), NILZ 295
The synthetic route of 102359-00-2 has been constantly updated, and we look forward to future research findings.
