To 1-[(2-isopropyl-5-methyl-phenyl)carbamothioyl]-3-[3-[4-[1-[4-(trifluoromethoxy)phenyl]-1,2,4-triazol-3-yl]phenyl]propyl]urea (F21) (0.110 g, 0.184 mmol) in a 25 mL vial equipped with a stir bar and Vigreux column was added sodium acetate (0.0600 g, 0.735 mmol), ethanol (2 mL) and methyl bromoacetate (0.0250 mL, 0.276 mmol). The reaction was heated to 70° C. overnight. The reaction was cooled and diluted with dichloromethane. The layers were separated and the aqueous layer was extracted with dichloromethane. The organic layers were poured through a phase separator and concentrated. Purification by flash column chromatography using 0-30% ethyl acetate/B, where B=1:1 dichloromethane/hexanes, as eluent provided a solid which was dried overnight at 50° C. in vacuo to afford the title compound as a white solid (0.0791 g, 68%).
