Experimental procedure: A solution of p-(dimethylamino)cinnamic acid 1 (500 mg, 2.6 mmol) and CDT (480 mg, 2.9 mmol) in CH2Cl2 (50 mL) and acetone (10 mL) is stirred at room temperature for 4 h. The solution is then washed with saturated aqueous NaHCO3 (3 x 20 mL) and brine (20 mL) and dried (Na2SO4). The organic layer is concentrated under reduced pressure to give (dimethylamino)cinnamoyl triazole 2 (484 mg, 81%).
  To a solution (1R, 2R)-trans-cyclohexanediol (3.0mg, 0.026 mmol) and 2 (22 mg, 0.1 mmol) in CH2Cl2 (2 mL) is added a solution of DBU (ca. 0.04 mL, 0.01 mol/L in CH2Cl2). The solution is then stirred at room temperature for 6 h, and it is the concentrated under reduced pressure. The product is isolated by preparative TLC (silica gel, hexane:EtOAc = 2:1) to give the diester 3 (10.1 mg, 84%) as a yellow solid.
