실험 절차

To a stirred solution of 3-4 (5 g, 13 mMol), HOBT (1.9 g, 14.3 mMol), and 1-methyl-1H-imidazole-4-carboxylic acid (2 g, 15.6 mMol) in anhydrous DMF (100 mL) was added EDC (2.7 g, 14.3 mMol). The solution was stirred overnight at ambient temperature. The solution was then treated with 24 mL of acetic acid and was heated to 80° C. in an oil bath for 5 hours. Upon cooling to room temperature, an equal volume of water was added and the resulting suspension was filtered and washed with copious amounts of water. The collected solid was dried azeotropically with toluene three times to yield 13-1 as a tan solid. Mass (M+1) calculated: 475.1877 observed: 475.1871
