実験手順

To a solution of N′-(4-fluoro-thiobenzoyl)-hydrazinecarboxylic acid tert-butyl ester (1.97 mmol) in CH2Cl2 is added trifluoroacetic acid (3 mL) and thioanisole (2.7 mmol). The mixture is stirred at room temperature for 1 hour. After evaporation of the solvent the mixture is purified by automated column chromatography (hexanes/EtOAc) to yield 4-fluoro-thiobenzoic acid hydrazide trifluoroacetic acid salt: 1H NMR (400 MHz, CDCl3) δ 9.5 (bs, 3H), 7.8-7.76 (m, 2H), 7.05 (t, J=8.4 Hz, 2H); LC/MS: (ES+) 171 (M+1)+.
