Procedure
A solution of 5 g of methyl 1-methyl-1H-imidazole-5-carboxylate and 22.5 g of paraformaldehyde in 50 ml of methanol was heated at 140° C. for 60 hours under a sealed tube condition. The precipitate was removed by filtration and the solution was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: chloroform-methanol) to obtain 4 g of methyl 2-(hydroxymethyl)-1-methyl-1H-imidazole-5-carboxylate as a white solid.
