Base-induced cyclization of N′-cyanomethyl-N′-methylurea gives 1-methyl-4-amino-imidazol-2-one, this in turn is condensed with 3-hydroxy-2-phenylacrolein to yield an imidazo[4,5-b]pyridine which is converted into 2-amino-1-methyl-6-phenyl-1H-imidazo[4,5-b]pyridine (PHIP).
的碱诱导的环化Ñ '-cyanomethyl- ñ '甲基脲给出1-甲基-4-氨基-咪唑-2-酮,这反过来又被冷凝与3-羟基-2- phenylacrolein,得到咪唑并[4,5 - b ]吡啶,其被转换成2-氨基-1-甲基-6-苯基-1 ħ -咪唑并[4,5- b ]吡啶(PHIP)。
