Versuchsvorschrift

A solution of 1-(6-(3-aminopropanoyl)-2-benzothiazolyl)-3-ethylurea (0.033 g, 0.10 mmol) in 1 mL anhydrous DMF was treated with triethylamine (0.028 mL, 0.20 mmol, 2.0 eq) at room temperature. It was stirred for about 5 min, followed by the addition of benzoyl chloride (0.014 mL, 0.12 mmol, 1.2 eq). It was stirred for about 2.5 hours, quenched with MeOH, filtered, concentrated, and purified by HPLC to give the desired compound 0.011 g (28%). LC/MS 396.7 (M+1); LC retention time 2.74 min.
