実験手順

Triethylamine (34 μL, 0.25 mmol) and N-(tert-butoxycarbonyl)-N-{4-(dimethylazaniumylidene)-1,4-dihydropyridin-1-ylsulfonyl}azanide (49 mg, 0.16 mmol) were added in series to a solution of dimethylcarbamic acid 3-(3-aminobenzyl)-6-chloro-4-fluoromethyl-2-oxo-2H-1-benzopyran-7-yl ester (compound 1h-1-3F) (33 mg, 0.082 mmol) in anhydrous dichloromethane (1.0 mL), and the mixture was stirred at room temperature overnight. The reaction mixture was then poured into water and extracted with ethyl acetate. The organic extract was washed with saturated saline and dried over magnesium sulfate. A crude solid was then obtained by vacuum concentration, and purified by preparative TLC (ethyl acetate:hexane=1:2) to yield the title compound (30 mg, 63%) as a white powder.
