Procedure

To a stirred solution of 10 parts of 4-[(1H-imidazol-1-yl)methyl]benzenamine in 180 parts of 1,2-dichloroethane were added dropwise 3.9 parts of 4-methylene-2-oxetanone. After stirring for 1/2 hour at room temperature, the precipitate was filtered off, washed with 1,2-dichloroethane and dried, yielding 9.8 parts (74.8%) of N-[4-(1H-imidazol-1-ylmethyl)phenyl]-3-oxobutanamide; mp. 175° C. (interm. 57).
