Brief introduction of 952059-69-7

952059-69-7, 8-Chloro-3-methoxy-1,5-naphthyridine is a naphthyridine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

2-(2-((7-Methoxy-l,5-naphthyridin-4-yl)(methyl)amino)ethyl)-6-(4- methylthiophen-2-yl)pyridazin-3(2H)-one. A suspension of 2-(2- (methylamino)ethyl)-6-(4-methylthiophen-2-yl)pyridazin-3(2H)-one (275 mg, 1103 mumol) and 8-chloro-3-methoxy-l,5-naphthyridine (193 mg, 993 mumol) in iPrOH (5 mL) was heated to 100 C for 18 h in an appropriately sealed vial. The mixture was partitioned between CH2Cl2 (30 mL) and IM NaOH (10 mL), and the organic dried over MgSO4. After concentration under reduced pressure, the organic residue was dissolved in iPrOH (2 mL) and the rsulting crystalized solid was washed with iPrOH (2x 0.5 mL) then dried under reduced pressure. MS (ESI pos. ion) m/z (MH+): 408. Calc’d exact mass for C2ieta2iN5O2S: 407. 1H NMR (400 MHz, Chloroform-d) delta ppm 2.26 (s, 3 H) 3.22 (s, 3 H) 3.83 (s, 3 H) 4.51 (t, J=5.77 Hz, 2 H) 4.75 (t, J=5.77 Hz, 2 H) 6.55 (d, J=5.52 Hz, 1 H) 6.60 (d, J=9.54 Hz, 1 H) 6.91 (s, 1 H) 6.97 (s, 1 H) 7.19 (d, J=9.54 Hz, 1 H) 7.32 (d, J=3.01 Hz, 1 H) 8.32 (d, J=5.52 Hz, 1 H) 8.46 (d, J=2.51 Hz, 1 H).

The synthetic route of 952059-69-7 has been constantly updated, and we look forward to future research findings.
