CAS:3-(2-Chloroethyl)-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one is a chemical compound that is used to synthesize the drug paliperidone. The reaction time of this synthesis reaction is high and the yield is high. The conformation of the product can be predicted with theory. The hydrochloride salt of the product has a higher solubility in water than does the free base form. The reactants are 3-(2-chloroethyl) pyridine and 2-methyl 4H pyrido[1,2-a]pyrimidin-4-one, which are both cheap and easily accessible. This synthesis can be carried out using solvents such as phosphorus oxychloride or carbonyl oxychloride. The dihedral angle for this molecule is around 100 degrees, which makes it a planar molecule. This compound reacts with pyridine
