Synthetic Route of 127446-34-8 , The common heterocyclic compound, 127446-34-8, name is N-(6-Chloro-3-formylpyridin-2-yl)pivalamide, molecular formula is C11H13ClN2O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Step 1 : Sodium thiomethoxide (1 .37 g, 19.5 mmol, 1 .50 eq) is added to N-(6-chloro-3-formyl- pyridin-2-yl)-2,2-dimethyl-propionamide (Org Process Res. Dev. 2009, 13, 555) (1 .87 g, 7.79 mmol) in THF (50 mL) in a round-bottom flask and the solution is stirred at 50 C for 2 h. The reaction mixture is diluted with EtOAc and washed with brine. The organic layer is dried over MgS04, filtered and concentrated under reduced pressure to afford intermediate 5001 A.
The synthetic route of 127446-34-8 has been constantly updated, and we look forward to future research findings.
