実験手順

33.0 g of ammonium carbonate are added at room temperature to a solution of 15.5 g of N,α-bis-formyl-N-(1,2,3,4-tetrahydronaphthalen-1-yl)glycine methyl ester in 300 ml of xylene. The mixture is heated to 70° C. for 1 hour then the temperature is raised to 120° C. for 3 hours. After concentration the 1-(1,2,3,4-tetrahydronaphthalen-1-yl)-5-imidazolecarboxylic acid methyl ester precipitates from the solution, having a melting point of 63° C.
