Procedure

To 6-methylpyridine-2-carboxaldehyde (2.0 g, 16.5 mmol) in dry THF (55 mL) at 0° C. under nitrogen, add a solution of 3M methyl magnesium bromide in ether (6.0 mL, 18.0 mmol) dropwise with stirring. After 1 h at 0° C., quench with saturated aqueous NH4Cl, extract three times with EtOAc, dry over anhydrous Na2SO4 and concentrate in vacuo to give the desired intermediate (crude, 2.3 g).
