As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO208,mainly used in chemical industry, its synthesis route is as follows.,952059-69-7
Example 40 (Method C4)Synthesis of N1-(7-methoxy-l,5-naphthyridin-4-yl)-N4-(4-phenylphthalazin-l- yl)benzene-l,4-diamine; In a 20 mL sealed tube was dissolved 8-chloro-3-methoxy-l,5-naphthyridine (70 mg, 360 mumol) in DMF (2.00 mL). To this was added Nl-(4-phenylphthalazin-l-yl)benzene-l,4- diamine (124 mg, 396 mumol) and the reaction mixture was stirred at 70 0C for 17 h. Upon cooling to RT, the mixture was dissolved in DMF and purified using Gilson reverse phase chromatography. The product fractions were combined, concentrated and the resulting crude was extracted into DCM, washed 1 x sodium .carbonate, 1 x H2O, dried withNa2SO4, filtered through fritted funnel, concentrated to yield Nl-(7-methoxy-l,5- naphthyridin-4-yl)-N4-(4-phenylphthalazin-l-yl)benzene-l,4-diamine as light yellow solid. MS [M+H]=471.0; Calc’d 470.5 for C29H22N6O.
With the complex challenges of chemical substances, we look forward to future research findings about 8-Chloro-3-methoxy-1,5-naphthyridine,belong naphthyridine compound
