Downstream synthetic route of 14805-29-9

As the paragraph descriping shows that 14805-29-9 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14805-29-9,exo-Hexahydro-1H-4,7-methanoisoindole-1,3(2H)-dione,as a common compound, the synthetic route is as follows.

A mixture of bicyclo[2.2.1]heptane-2,3-di-exo-carboximide (prepared as described in Chem. Pharm. Bull., 1991 p 2288; 1.0 g, 6.05 mmol), ethyl chloroacetate (1.3 mL, 12.1 mmol), TBAB (39 mg, 0.12 mmol) and potassium carbonate (1.17 g, 8.48 mmol) were irradiated in microwawe for 10 min at 150 C. (150 W). The mixture was then diluted with water and EtOAc. Organic phase was separated, and aqueous phase was extracted with EtOAc (3¡Á15 mL). Combined organic phases were washed with brine (1¡Á15 mL), dried over Na2SO4, filtered and concentrated to afford the title compound as a brown oil (1.74 g, 114%)., 14805-29-9

Example 2To the reaction mixture containing Compound (C) which was obtained in the above Example 1 were added tetra-n-butyl ammonium hydrogen sulfate (0.62 g, 1.83 mmol), (3aR,4S,7R,7aS)-hexahydro-4,7-methano-2H-isoindole-1,3-dione [Compound (D)] (11.3 g, 68.4 mmol), potassium carbonate (7.6 g, 55.0 mmol) and water (0.4 g), and the resulting mixture was reacted under reflux for 3 hours. Then, the reaction mixture was cooled to room temperature, and water (200 g) was added to the mixture. The mixture was separated with a separating funnel, and the toluene layer was washed with 2.3percent (W/W) brine (175 g). Further, active carbon (0.9 g) was added to the toluene solution, and the mixture was stirred for 1 hour. The active carbon was removed by filtration to give a toluene solution containing (3aR,4S,7R,7aS)-2-{(1R,2R)-2-[4-(1,2-benzisothiazol-3-yl)-piperazin-1-ylmethyl]cyclohexylmethyl}-hexahydro-4,7-methano-2H-isoindole-1,3-dione (2-[[(1R,2R)-2-[[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]methyl]-cyclohexyl]methyl]hexahydro-(3aS,4R,7S,7aR)-4,7-methano-1H-isoindole-1,3(2H)-dione) [Compound (E)] (266.5 g). The yield of Compound E was 94.3percent. The yield of Compound (E) was calculated based on the analytical result that the content of the compound in the toluene solution was 7.9percent (w/w) (which was calculated by LC absolute calibration curve method). And, the production rate of by-product (R) was 0.12percent (which was calculated with the above formula (a))., 14805-29-9
