실험 절차
0.25 g of (7-bromoacetyl-4-methoxy-benzothiazol-2-yl)-carbamic acid methyll ester (0.0007 Mol) and 0.33 g of tert-butoxycarbonylguanidine (0.0021 Mol) were heated to reflux in acetonitril (3 ml) for 3 hrs. After evaporation of the solvent the residue was triturated with water (10 ml) and filtered. The filtrate was evaporated and the residue subjected to column chromatography (silicagel, ethyl-acetate/hexanes 1:1) to yield the title compound as a white solid (17%); F.p.: 255-265° C.
