2318-25-4, Name is Ethyl 3-ethoxy-3-iminopropionate hydrochloride, 2318-25-4, belongs to esters-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows.
.To a mixture of 281 g of Compound (I-4) suspended in 1.6 liters of acetonitrile, 210 ml of triethylamine was added while stirring at a room temperature. Following stirring for 30 minutes, 318 g of the foregoing Intermediate (I-3) and 36 ml of acetic acid were added in this order to react them. After reacting for 10 hours, 3 liters of water was added and stirring was continued. Precipitated crystals were collected by filtration. The crystals were washed with water and dried. As a result, 324 g (yield 71percent) of the objective Intermediate (I-5) was obtained, as a white crystal.
Statistics shows that Ethyl 3-ethoxy-3-iminopropionate hydrochloride is playing an increasingly important role. we look forward to future research findings about 2318-25-4.
