실험 절차

10 g of 1-benzyl-2-guanidinomethyl-indoline hemisulphate (obtainable from ethyl indoline-2-carboxylate by N-benzylation, reduction and reaction with SOCl2 to give 1-benzyl-2-chloromethyl-indoline, reaction of the latter with potassium phthalimide and hydrolysis of the reaction product, and reaction of this product with S-methyl-isothiourea hemisulphate) are dissolved in 200 ml of ethanol and hydrogenated over 3 g of 5% Pd/C at 20° C. and 1 atmosphere until the reaction ceases. After filtering and evaporating the filtrate, 2-guanidinomethyl-indoline hemisulphate is obtained.
