65632-62-4,65632-62-4, (S)-1-((Benzyloxy)carbonyl)hexahydropyridazine-3-carboxylic acid is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step A: Preparation of l-(phenylmethyl) hydrogen tetrahydro-2-nitrosopyridazine-1 ,(35)(2H)-dicarboxylateA solution of sodium nitrite (1.03 g, 15.0 mmol) in 8 rnL of water was added dropwise over 10 minutes to a suspension of l-(phenylmethyl) hydrogen tetrahydropyridazine-l,(35)(2H)-dicarboxylate (2.64 g, 10.0 mmol; prepared as described inCoats et al. J. Org. Chem. 2004, 69, 1734) in 1 N hydrochloric acid (30 mL) at 4 0C. After3.5 h the reaction mixture was diluted with ethyl acetate (40 mL), and the layers were separated. The aqueous layer was extracted with ethyl acetate (2 X 20 mL), and the combined organic layers were dried over sodium sulfate, filtered and concentrated under reduced pressure to give 3.14 g of the title compound as a yellow oil. This compound was carried on without further purification or characterization.
The synthetic route of 65632-62-4 has been constantly updated, and we look forward to future research findings.
