130049-82-0, Adding a certain compound to certain chemical reactions, such as: 130049-82-0, 3-(2-Chloroethyl)-6,7,8,9-tetrahydro-9-hydroxy-2-methyl-4H-pyrido[1,2-a]pyrimidine-4-one, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 130049-82-0, blongs to pyrimidines compound.

79 g of 6-Fluoro-3-(4- piperidinyl)-l,2-benzisoxazole hydrochloride, 375 ml of methanol, and 78.2 g of triethyl amine were charged in a reaction vessel at 25-300C. The reaction mixture was stirred for 5 minutes. 75 g of the compound of formula II and 375 ml methanol were added to the above mass. The reaction mixture was heated to 60-630C and then maintained at 60-630C to achieve the desired conversion. The reaction mixture was then cooled to 40-450C. Methanol was distilled off under reduced pressure up to two volumes. 375 ml of water was added to the reaction mixture and stirred for 20-30 minutes at 25-300C. The solid was filtered and washed twice with 150 ml water followed by 2×150 ml acetone to obtain 87 g crude paliperidone. (Purity of compound of formula I >97%).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,130049-82-0, its application will become more common.
