Some common heterocyclic compound, 14062-19-2, name is Ethyl p-Tolylacetate, molecular formula is C11H14O2, 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. Product Details of 14062-19-2
LiHMDS was prepared by the treatment of HMDS (2.432 g, 15.07 mmol) with n-BuLi (1.6 M solution in hexane, 9.4 mL, 15 mmol) in dry THF (30 mL) at 0C for 30 min. To a solution of ethyl p-tolylacetate (1.778 g, 9.98 mmol) in dry THF (30 ml) was added the LiHMDS at -78C. The mixture was stirred at -78C for 30 min. To the mixture, ethyl cyanoformate (1.110 g, 11.20 mmol) was added at -78C, and then the mixture was allowed to warm to 0C for 80 min. 10% HCl was added at 0C, and the mixture was extracted twice with CH2Cl2. The combined organic extracts were dried over Na2SO4. After removal of the solvent, the residue was purified by column chromatography using silica gel (hexane/acetone 25/1) to afford 7 as a colorless oil (2.396 g, 96%). 1H NMR spectra data were identical to those reported in the literature.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 14062-19-2, its application will become more common.
