Procedure

2-Amino-ethanesulfonic acid {2-[3-(2-cyclopentanecarbonyl-4-methyl-phenyl)-ureido]-thiazol-4-ylmethyl}-amide (104 mg, 83%) was prepared from 1-(4-aminomethyl-thiazol-2-yl)-3-(2-cyclopentanecarbonyl-4-methyl-phenyl)-urea (90 mg, 0.25 mmol) and 2-(1,3-Dioxo-1,3-dihydro-isoindol-2-yl)-ethanesulfonyl chloride (70 mg, 0.25 mmol) following the general procedure T. This intermediate was deprotected by heating with excess of hydrazine (0.2 mL, 1.0 M. in THF).
