With 3-((1R,2R)-2-(piperidin-1-yl)cyclohexylamino)-4-(4-(trifluoromethyl)phenylamino)cyclobut-3-ene-1,2-dione; In dichloromethane; at 20℃; for 90h; | General procedure: To a stirred solution of 21.07 mg of squaramide 11a (0.05 mmol, 10 mol%) in 4 mL of DCM were added first 0.056 mL of methyl 3,3,3-trifluoropyruvate (3, 0.55 mmol) and than the phenol 4 (0.5 mmol). The solution was stirred at room temperature until the reaction completion. Afterwards, the solution was concentrated under vacuum and the residue was purified by flash chromatography on silica gel to give the desired product 1. |
