Chen, Fang-tao published the artcileSynthesis of aldehyde-amines type sulfide 808 and DHP, Safety of 3,5-Diethyl-1-phenyl-2-propyl-1,2-dihydropyridine, the publication is Yingyong Huagong (2013), 42(4), 765-767, database is CAplus.
Aniline reacted with n-butyraldehyde under different conditions afforded condensation products 808 and DHP (808HP). By using gas chromatog., products were verified by compared to standard samples, and purity was decent. This process achieved improved yield and simplified operations, reduced costs, and provided a new approach in industrial production
Yingyong Huagong published new progress about 34562-31-7. 34562-31-7 belongs to pyridine-derivatives, auxiliary class Pyridine,Benzene, name is 3,5-Diethyl-1-phenyl-2-propyl-1,2-dihydropyridine, and the molecular formula is C18H25N, Safety of 3,5-Diethyl-1-phenyl-2-propyl-1,2-dihydropyridine.
