Application of 914612-23-0, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 914612-23-0 as follows.
Alternative synthesis for (S)-3-(6-Benzyl-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-4-yloxy)-pyrrolidine-1-carboxylic acid tert-butyl ester To a solution of (S)-3-hydroxypyrrolidine-1-carboxylic acid tert-butyl ester (6.21 g, 33.16 mmol) and 6-benzyl-4-chloro-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidine (9 g, 34.65 mmol) in 2-Me-THF (100 mL) was added under nitrogen tBuOK (8.17 g, 72.95 mmol). The mixture was stirred at rt for 25 min. The mixture was quenched with H2O. The organic layer was washed with brine. The resulting organic solution was concentrated in vacuo to provide (S)-3-(6-benzyl-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-4-yloxy)-pyrrolidine-1-carboxylic acid tert-butyl ester (12.6 g, 89% yield) as a yellow gum.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,914612-23-0, its application will become more common.
