Procedure

175 mg of 2-guanidino-4-methyl-thiazole-5-carboxylic acid, 2.6 ml of DMF, 0.29 ml of N-MM and 332 mg of HBTU are stirred at room temperature (RT) for one hour, treated with 197 mg of butyl (3-amino-propoxy)-acetate hydrochloride and stirred at RT for a further 18 hrs. For the working up, the mixture is diluted with ethyl acetate, washed with dilute sodium carbonate solution, dilute sodium chloride solution and saturated sodium chloride solution, dried and evaporated in a vacuum. Chromatography on silica gel with methylene chloride-alcohol gives 162 mg of butyl {3-[(2-guanidino-4-methyl-thiazole-5-carbonyl)-amino]-propoxy}-acetate, mass spectroscopy (MS): 372 (M+H)+.
