Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 6960-22-1, name is 6-Methylnicotinamide. This compound has unique chemical properties. The synthetic route is as follows. Recommanded Product: 6-Methylnicotinamide
Example 4: Synthesis of 106Step 1 :3.00 g (22.0 mmol) 6-methylnicotinamide is dissolved in 10 ml THF under argon-atmosphere and 34 ml (34 mmol; 1.5 eq.) 1 M lithium aluminum hydride in THF are added. After 45 min additional lithium aluminum hydride (1.22 g; 1.5 eq.) in 40 ml THF is added. The reaction mixture is heated to 60C for 24 h under stirring. The reaction mixture is carefully quenched under stirring with isopropyl alcohol, methanol and finally water at 0C. The solvent is removed under vacuum. After addition of 100 ml 2N NaOH solution and 100 ml DCM the white precipitate is centrifuged off and the aqueous layer is extracted 4 times with 60 ml DCM. The combined organic layers are dried over magnesium sulphate and the solvent is removed under reduced pressure yielding 1.57 g (12.9 mmol; 58%) of the amine 2 which is used without further purification for subsequent reaction steps.
