실험 절차

To a dry flask charged with a stir bar was added 2-(2-amino-ethyl)-isoindole-1,3-dione hydrochloride salt (100 mg, 0.53 mmoles) (Burgess, K.; Ibarzo, J. D.; Linthicum S.; Russell, D. H.; Shin, H.; Shitangkoon, A.; Totani, R.; and Zhang, A.; J. Am. Chem. Soc. 1997, 119, 1556), 1,3-Dimethyl-2-oxo-2,3-dihydro-1H-benzoimidazole-5-carbaldehyde (156 mg, 0.68 mmoles), MP-carbonate (254 mg, 0.79 mmoles) (Argonaut Tech), 3 Å sieves (1.2 g) and 4 mL of dichloromethane. The flask was sealed with a plastic cap and the resulting mixture was stirred for 48 hours at 22° C. The mixture was filtered through a nylon disk via syringes, rinsing with dichloromethane and the filtrate was concentrated to give 154 mg of 2-{2-[(1,3-Dimethyl-2-oxo-2,3-dihydro-1H-benzoimidazol-5-ylmethylene)-amino]-ethyl}-isoindole-1,3-dione as a light yellow solid.
