Chloropyrazine → HCID 178420800, compound

Participants

Reaction Steps

1 g (8.9 mmol) of histamine and 1.03 g (8.9 mmol) of 2-chloropyrazine are brought to reflux in 20 ml of 2-propanol for 72 h, evaporated and the crude solid residue is chromatographed through silica gel, using chloroform/methanol mixtures (1%, 5%, 10% and 20% respectively). The product is converted to the dioxalate in absolute ethanol and addition of ether gives the title compound which is recrystallized from a 2-propanol/diethyl ether mixture in the form of a white solid.
