Related Products of 4430-75-5, These common heterocyclic compound, 4430-75-5, name is Octahydro-2H-pyrido[1,2-a]pyrazine, 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.
Step A Ethyl 3-(octahydro-2H-pyrido[1,2-a]pyrazin-2-yl)propionate A solution of 7 g of octahydro-2H-pyrido[1,2-a]pyrazine and 15 ml of ethyl acrylate in 100 ml of acetonitrile is refluxed for 24 hours and then concentrated to dryness in vacuo to yield the expected product.
The synthetic route of 4430-75-5 has been constantly updated, and we look forward to future research findings.
