Participants

Reaction Steps

A solution of (E)-N,N-dimethyl-3-(2-methyl-1H-imidazol-4-yl)-2-propenamide (340 mg) in methanol (10 ml) and HCl-saturated ethanol (2 ml) was added to a previously hydrogen-saturated suspension of 10% palladium on charcoal (50% paste with water) (35 mg) in methanol (10 ml) and the resulting suspension stirred at room temperature under hydrogen for 4 h. The mixture was filtered, concentrated in vacuo to ca. 5 ml and ethyl acetate (ca. 40 ml) was added, precipitating the title compound (275 mg) as white flakes, t.l.c. (System A 89:10:1), Rf 0.14. Addition of further ethyl acetate (40 ml) to the mother liquors precipitated further title compound (31 mg).
