실험 절차

Step B Urea Formation: Addition of ethyl isocyanate (0.5 mL, 6.5 mmol) to 7-(Cyclohexylmethyl-amino)-1-ethoxycarbonylmethoxy-3,8-dithia-cyclopenta[a]indene-2-carboxylic acid methyl ester (60 mg, 0.13 mmol) was carried out following a procedure similar to that delineated in Step B, Example 27, with the following exceptions: co-solvent (DCE), addition of catalytic DMAP, temperature (70° C. vs. ambient), and total reaction time (100+ hours), affording 30 mg of 7-(1-Cyclohexylmethyl-3-ethyl-ureido)-1-ethoxycarbonylmethoxy-3,8-dithia-cyclopenta[a]indene-2-carboxylic acid methyl ester (43% yield).
