Versuchsvorschrift
1.68 g (0.01 mol) of 1-isopropyl-5-carbmethoxyimidazole is suspended in 5 ml of water. To the suspension are added 0.8 g (0.02 mol) of sodium hydroxide and 4 ml of ~37% aqueous formaldehyde. The resultant mixture is heated to reflux for 2 hours. After completion of the reaction, the solvent is stripped off, and the residue is extracted with ethyl acetate and concentrated to give 1-isopropyl-5-hydroxymethylimidazole as a solid, m.p. 83°-84° C.
