2-Chloro-5-(3-trifluoromethyl-benzoylamino)-benzoic acid (0.524 g, 1.53 mmol, 1.1 equiv) was combined with 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) (0.305 g, 1.74 mmol, 1.25 equiv) and diluted with DCM (10 mL). This was immediately treated with 4-methyl morpholine (0.458 mL, 4.16 mmol, 3 equiv) and allowed to stir at ambient temperature for 1 hour. Intermediate 68 (0.3 g, 1.38 mmol, 1 equiv) was then added in one portion. Stirring was continued overnight. After 18 h, reaction solvents were removed and resulting crude solids were purified via silica gel chromatography. Eluting with 1:1 EtOAc in Hexanes afforded desired product. Beige solids (0.19 g, 26%).
