実験手順

To a mixture of 1-amino-3-(4-fluoro-3-methoxyphenyl)-3-methylbutan-2-one hydrochloride (35.4 g, 0.135 mol) and 4-fluorophenyl isothiocyanate (21.75 g, 0.142 mol) in DCM (500 mL) was added Et3N (37.6 ml, 0.27 mol) at 0° C., and the reaction mixture was warm to room temperature over 1 h. The reaction mixture was washed with 1N HCl (500 mL), satd NaHCO3 (500 mL) and brine (500 mL) successively, dried over MgSO4, filtered and concentrated under reduced pressure give a residue, which was triturated with Hex-EtOAc to afford 1-(3-(4-fluoro-3-methoxyphenyl)-3-methyl-2-oxobutyl)-3-(4-fluorophenyl)thiourea (45 g, 88%) as a white solid. 1H NMR (400 MHz, CDCl3) δ 7.85 (b, 1H), 7.25 (m, 2H), 7.15 (m, 2H), 7.05 (m, 1H), 6.79 (m, 2H), 6.67 (b, 1H), 3.88 (s, 3H), 1.54 (s, 6H).
