The reactions of N-(pyrimidin-2-yl)imines of methyl trifluoropyruvate with trimethyl phosphite afforded methyl 3-fluoroimidazo[1,2-a]pyrimidin-2-carboxylates, which were transformed into N-substituted methyl 3-aminoimidazo[1,2-a]pyrimidine-2-carboxylates by the reactions with amines.
N-(吡啶-2-基)亚胺与三氟丙酮酸甲酯的反应生成了甲基3-氟噁唑[1,2-a]吡啶-2-羧酸酯,随后与胺反应转化为N取代的甲基3-氨基噁唑[1,2-a]吡啶-2-羧酸酯。
