実験手順: Ethyl-2-ethoxy-2-iminoacetate (1.318 g, 9.08 mmol) and phenyl acetic acid hydrazide (1.364 g, 9.08 mmol) were mixed together in ethanol (20 ml) and stirred at 80° C. for 1 h. Ethanol was evaporated. The residue was dissolved in n-butanol (20 ml). The reaction mixture was stirred at 150° C. for 20 h, then solvents were evaporated. Ethanol was evaporated The residue was dissolved in n-butanol (20 ml) The reaction mixture was stirred at 150° C. for 20 h solvents were evaporated

実験手順: 2-amino-5-hydroxy-benzoic acid (15 mmol) are suspended in ethanol (water free, 600 ml) and heated up to 60° C. and stirred. Then triethylamine (30 mmol) is added and a clear solution is formed. Ethoxy-imino-acetic acid ethyl ester (1 6.5 mmol) is added at 60° C. and after 15 minutes another portion of triethylamine (15 mmol) is added and the mixture stirred for another 30 minutes. The mixture is cooled down to RT and left at RT without stirring over night. The solid material formed was filtered off, washed with ethanol/ether and dried (vacuum). A pale brown powder with mp. 258-260° C. (decomposition) is obtained. a clear solution is formed is added the mixture stirred for another 30 minutes The mixture is cooled down to RT left at RT without stirring over night The solid material formed was filtered off washed with ethanol/ether dried (vacuum) A pale brown powder with mp. 258-260° C. (decomposition) is obtained

実験手順: Nitriloacetic acid ethyl ester (83 mmol) was dissolved in diethyl ether (water free, 25 ml) and ethanol (water free, 85 mmol) was added and the stirred mixture cooled to 40 ° C. At this temperature, HCl (gaz, dried through concentrated sulfuric acid; 18 g total consumption) was bubbled into the solution over 1 hour. The cooling bath was removed and at 0° C. the reaction mixture warmed up quickly (additional cooling required) and the product precipitated. The solid material was filtered off, washed with diethyl ether and dried.
