Application of 102359-00-2,Some common heterocyclic compound, 102359-00-2, name is 2-Oxoindoline-5-carboxylic Acid, molecular formula is C9H7NO3, 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.

An oven-dried round-bottom flask was charged with 2-oxoindoline-5- carboxylic acid (89 mg, 0.500 mmol), TBTU (193 mg, 0.600 mmol), HOBt hydrate (81 mg, 0.600 mmol), DIPEA (0.13 mL, 0.750 mmol) and DMF (3.0 mL) and stirred for 5 minutes. Methyl amine (0.75 mL of a 2.0 M solution in THF) was then added and reaction was stirred for 4 hours at which time NaHCO3(Sat ) (2mL) was added. Solvents were removed in vacuo and the residue was purified by column chromatography (silica gel, 92:8 CH2Cl2ZMeOH) to give the title compound (11 mg, 12 %). IH NMR (400 MHz, CD3OD) delta ppm 7.69 – 7.75 (m, 2 H), 6.94 (d, J=8.1 Hz, 1 H), 3.58 (s, 2 H), 2.97 (s, 3 H); MS ESI 191.0 [M + H]+, calcd for [C10H10N2O2 + H]+ 191.08.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Oxoindoline-5-carboxylic Acid, its application will become more common.
