Versuchsvorschrift

To a solution of 2-(4-chloro-3-methoxyphenyl)-2-methylpropanehydrazide hydrochloride (6.88 g, 0.02 mol) and 4-fluorophenylisothiocyanate (3.96 g, 0.03 mol, 1.05 eq.) in DCM (500 mL) at 0° C. was added Et3N (7 mL, 1.29 mol, 2.0 eq.) and the resulting solution was stirred for 1.5 h at room temperature. The reaction mixture was washed with 1M HCl, satd NaHCO3 and brine, dried over MgSO4, filtered and concentrated in vacuo. The residue was triturated with DCM/Et2O, collected by filtration and dried to give 2-(2-(4-Chloro-3-methoxyphenyl)-2-methylpropanoyl)-N-(4-fluorophenyl)hydrazine carbothioamide (8.13 g, 83% as a white solid. 1H NMR (400 MHz, CDCl3) δ 7.32-7.30 (d, 1H), 7.25-7.22 (m, 2H), 7.01-7.05 (t, 2H), 6.95-6.94 (d, 1H), 6.93-6.90 (dd, 1H), 3.88 (s, 3H), 1.64 (s, 6H).
