Ethyl 1-ethyl-3-phthalimidoacetate was prepared by condensation of ethyl 3-phthalimidoacetoacetate and acetaldehyde followed by reduction. The substituted acetoacetate was hydrolysed by dil.HCl and the corresponding aminoketone treated with potassium thiocyanate to yield 2-mercapto-4 (or 5)-propylimidazole. The later was oxidised to the corresponding imidazole.
