実験手順
To a suspension of 1,2-dihydro-3-(1-imidazolyl)-6-carboxy-naphthalene (500 mg) in DMF (10 ml) SOCl2 (2 ml) was added. Cooling in an ice bath, NH3 was passed through the reaction mixture, with stirring, for 4 hours. The reaction mixture was allowed to stand for 12 hours. The ammonium salt was filtered off and Et2O was added giving a precipitate which was chromatographed on silica gel with CHCl3 :CH3OH-CH3COOH (45:5:2.5) as eluant; 350 mg of 1,2-dihydro-3-(1-imidazolyl)-6-carbamoyl-naphthalene were obtained.
