These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6136-93-2, its application will become more common.

Some common heterocyclic compound, 6136-93-2, name is 2,2-Diethoxyacetonitrile, molecular formula is C6H11NO2, 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. Computed Properties of C6H11NO2

In a 2 L, three-neck round bottom flask (equipped with magnetic stir bar, thermometer, and addition funnel), charged diethoxyacetonitrile (111.1 g, 860 mmol) and methanol (620 mL, anhydrous) while under a steady nitrogen flow. Via an addition funnel, slowly charged 25 wt % solution of sodium methoxide (4.64 g, 86 mmol, 19.7 mL) in methanol. (Note: addition is slightly exothermic). The mixture was stirred for 15 h, at which point, the solvent was removed under vacuum (Note: starting material had not been completely converted according to NMR). The residue was dissolved in methanol and charged with a fresh sodium methoxide solution- same concentration/equivalents- and stirred another 15 h). The solvent was removed under vacuum and the residue was dissolved in diethyl ether (1.0 L), with the organic phase washed with water (3 x 500 mL), then brine (1 x 300 mL). The organic layer was dried over magnesium sulfate, the salts filtered and the solvent reduced under vacuum to give 89.9 g of a crude mixture of methyl 2,2-diethoxyethanimidoate and un-reacted starting material (10-12 mol % by NMR) as a thin oil. Note that best yields of the imidate are obtained when the organic layer is stripped of at 400 mbar and 45 0C because of its volatility.The oil was dissolved in methanol (300 mL,) and placed into a 2 L round bottom flask (equipped with magnetic stir bar, reflux condenser) along with 1-(4-bromophenyl)methanamine (100.0 g, 537 mmol) and the mixture subjected to heating in a pre-heated oil bath. The mixture was stirred at 700C for 18 h and then allowed to cool. The solvent was removed to give 158.8 g of the desired intermediate (1) in 93.8% yield (based on 1-(4-bromophenyl)methanamine as limiting reagent).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6136-93-2, its application will become more common.
