Quality Control of 2-Chloro-6-(4-methoxybenzyl)-6,7-dihydro-5H-pyrrolo[3,4-b]pyridin-5-one

General procedure: Procedure A: To a solution of 5-bromo-2-(4-methoxybenzyl)isoindolin-1-one (1, 0.5 g, 1.5 mmol) in dioxane (10 mL) was added 7H-pyrrolo[2,3-d]pyrimidine (2, 0.27 g, 2.25 mmol) and potassium tert-butoxide (0.51 g, 4.52 mmol) followed by the addition of XantPhos (0.087 g, 0.15 mmol). The reaction mixture was degassed with argon for 15 min. Tris(dibenzylideneacetone)dipalladium(0) (0.14 g, 0.15 mmol) was then added and the reaction mixture was heated at 90 C. and maintained at that temperature for 12 h. (0193) Following heating, the reaction mixture was cooled and concentrated under reduced pressure. The concentrated reaction mixture was extracted in ethyl acetate. The organic layer was separated, dried over sodium sulphate, filtered and concentrated under reduced pressure. The residue obtained was purified by silica gel (100-200 mesh) column chromatography using 5% methanol in dichloromethane as eluent so as to afford 2-(4-methoxybenzyl)-5-(7H-pyrrolo[2,3-d]pyrimidin-7-yl)isoindolin-1-one (3). Yield: 0.21 g, 38%;

The synthetic route of 1440519-73-2 has been constantly updated, and we look forward to future research findings.

Synthetic Route of 1440519-73-2, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1440519-73-2, name is 2-Chloro-6-(4-methoxybenzyl)-6,7-dihydro-5H-pyrrolo[3,4-b]pyridin-5-one, molecular formula is C15H13ClN2O2, molecular weight is 288.7289, as common compound, the synthetic route is as follows.

To a solution of 2-chloro-6-(4-methoxy-benzyl)-6,7-dihydro-pyrrolo [3 ,4-b]pyridin-5-one (5.8 g, 20.0 mmol) in THF (50 mL) was added sodium hydride (60% in mineral oil, 1.7 g, 42.0 mmol) at room temperature. The resulting reaction mixture was stuffed for 30 mmbefore iodomethane (6.0 g, 42.0 mmol) was added. After stirring at room temperature overnight, the mixture was quenched with water and extracted with EtOAc. The organic layer was then washed with brine, dried over anhy. Na2SO4, filtered and concentrated in vacuo to give the crude product which was then purified by flash column chromatography (silica gel 20 g, 5% to 20% ethyl acetate in DCM). The title compound was obtained (3.8 g, 57%) as a white solid. MS: 316.2 (M+Hj.
