Application of 6136-93-2, These common heterocyclic compound, 6136-93-2, name is 2,2-Diethoxyacetonitrile, 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.
Diethoxyacetamidine hydrochloride was synthesized according to the literature method.3 To a solution of sodium methoxide (0.09 g, 1.6 mmol) in methanol (8.4 mL) was added diethoxyacetonitrile (2.00 g, 15.5 mmol) and the reaction mixture was stirred for 4 hours at room temperature. Solid carbon dioxide (0.5 g) was added and most of the methanol was evaporated. Diethyl ether was added and the sodium carbonate was removed by filtration.The filtrate was concentrated to afford methyl diethoxyacetimidate as a colorless oil (2.47 g, 99 % yield) which was used in the next step without further purification. The oil was dissolved in methanol (4mL), ammonium chloride (0.82 g, 15.3 mmol) was added, and the resultant mixture was stirred overnight at room temperature. The mixture was filtered and the methanol was removed in vacuo. The resulting oil was cooled to -78 C to form a solid and washed by diethyl ether (3 mL). The solid was filtered, warmed to ambient temperature and dried in vacuo to givedi ethoxyacetamidine hydrochloride (1.64 g, 58 %, 2 steps) as a white solid. 1H NMR (400 MHz, DMSO-d6): 9.15(br, 4 H), 5.29 (s, 1H), 3.61 (q, 4 H, J = 6.8 Hz), 1.18 (t, 6 H, J = 6.8 Hz).
The synthetic route of 6136-93-2 has been constantly updated, and we look forward to future research findings.
