実験手順
Methyl 2-aminothiazole-5-carboxylate (79 g, 0.5 mol) was added over a period of 2 hours to a boiling solution of amyl nitrite (117.0 g, 1.0 mol) in dioxan (1 liter). After refluxing for a further half hour, the solvent was removed under reduced pressure and the residue was steam distilled to give a yellow oil which, on trituration with petroleum ether, gave the desired product as a white solid (32.0 g), m.pt. 68° C.
