Synthetic Route of 2913-97-5, A common heterocyclic compound, 2913-97-5, name is N-(2-Oxoethyl)phthalimide, molecular formula is C10H7NO3, 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 Example 32A (12.1 g) in methanol (20 mL) was added L-isoleucine tert-butyl ester hydrochloride (13.0 g, 58 mmol), sodium cyanoborohydride (7.3 g, 116 mmol), and acetic acid (2 mL). The resulting solution was stirred for 3 hrs at 25° C. and the methanol removed under vacuum, dichloromethane (500 mL) added, and the solution extracted with aq. NaHCO3 (2.x.300 mL). Evaporation and purification of the organic layer gave 12.9 g of the title compound.
The synthetic route of 2913-97-5 has been constantly updated, and we look forward to future research findings.
