実験手順

2.86 g. of cyclohexylamino-ethanol are dissolved in 50 ml. of anhydrous ethyl acetate, whereupon gaseous hydrochloric acid is introduced until a pH value of 1 is reached. 4.61 g. of 3,4,5-trimethoxy-benzoyl chloride are added and the reaction mixture is refluxed under stirring for 8 hours. After cooling the precipitated crystalline mass is filtered by suction. 6.9 g. of N-2-ethyl-cyclohexylamino-3,4,5-trimethoxy-benzoate-hydrochloride are obtained. Mp.: 206°-208° C.
