This compound has unique chemical properties. The synthetic route is as follows. Quality Control of 2,4,6-Trichloropyrimidine-5-carbaldehyde
To a solution of 2,4,6-trichloro-pyrimidine-5-carbaldehyde (3.7 g, 17.5 mmol) in EtOH (50 mL) cooled to -78 C. was added methyl hydrazine (0.93 mL, 17.5 mmol) and TEA (8 mL). The mixture was stirred for 30 minutes at -78 C then 2 hr at 0 C. The solution was concentrated in vacuo without heating. To the reduced volume solution was added EtOAc and the solution washed with a sat NaHCO3 solution and concentrated in vacuo without heating. Filtration over a small silica gel plug (2:1 EtOAc:Hex) and concentration afforded the desired product as a yellow solid. It should be noted that the reaction with aromatic hydrazine compounds can be conducted at 0 C.
