Procedure

400 mg of 2-guanidino-4-methyl-thiazole-5-carboxylic acid, 463 mg of ethyl 4-amino-phenyloxyacetate hydrochloride, 6 ml of DMF, 0.67 ml of N-MM and 759 mg of HBTU are stirred at RT for 22 hrs. The working up and purification are effected as described in Example 1. Crystallization from acetonitrile (MeCN) gives 368 mg of ethyl {4-[(2-guanidino-4-methyl-thiazole-5-carbonyl)-amino]-phenoxy}-acetate, m.p. 223° C.;, MS: 378 (M+H)+.
