Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 936011-17-5, name is 5-Bromo-2-methoxyisonicotinaldehyde. A new synthetic method of this compound is introduced below., name: 5-Bromo-2-methoxyisonicotinaldehyde

Step 2: ethyl (2 E )-3-(5-bromo-2-methoxypyridin-4-yl)acrylate; 5 To solution of 5-bromo-2-methoxyisonicotinaldehyde (1 eq.) from step 1 and triethylphosphonoacatate (1.1 eq.) at O0C was added potassium tert-butoxide (1.0M in THF; l.leq.). The reaction mixture was allowed to warm to room temperature and stirred for Ih. The reaction was quenched with saturated aqueous NH4Cl and then extracted with EtOAc. The organic extract was washed with saturated NaHCO3, brine, dried over MgSO4, filtered and concentrated. Purification by column chromatography on silica gel (Combi-Flash by ISCO), eluting with Hex/EtOAc (O to 50% in 30min) afforded the desired compound.
