실험 절차

0.58 g of allyl(1-{4-[[4-(1-methyl-1H-imidazol-4-yl)phenylamino]-(2-oxobenzofuran-3-ylidene)methyl]phenyl}cyclopropyl)carbamate was dissolved in 20 mL of dichloromethane. The solution was freed from oxygen using argon. Then at RT, 0.52 mL of diethylamine and 0.058 g of tetrakis(triphenylphosphine)palladium (0) were added. The mixture was stirred for 2 hours at RT, the suspension was evaporated down with silica gel and chromatographed with dichloromethane/methanol (97:3) on silica gel 70 at a flow rate of 30 mL/min. The clean fractions were combined, evaporated down to the residue, dissolved in dichloromethane, filtered, and combined with diisopropyl ether. The dichloromethane was distilled off, the crystals formed were suction filtered and washed with diisopropyl ether. Yield: 0.26 g of yellow crystals, melting point 190° C.-191° C., as base. Rf value: 0.51 (dichloromethane/methanol (9:1)).
