Reaktionsschritte

To a solution of bis(3-(trifluoromethoxy)phenyl)methanamine (20 mg, 0.057 mmol) in CH2Cl2 (0.1 mL) was added 1-isothiocyanato-3-(trifluoromethyl)benzene (35 mg, 0.17 mmol). The reaction mixture was stirred at rt for 16 h. The reaction mixture was concentrated and the residue was purified by prep HPLC (phenomenex AXIA Luna 75×30 mm, 5μ column eluting with 10-90% ACN/H2O over 10 minutes containing 0.1% TFA; 40 mL/min, monitoring at 220 nm) to afford 1-(2-phenyl-1,1-bis(3-(trifluoromethoxy)phenyl)ethyl)-3-(3-(trifluoromethyl)phenyl)thiourea (Example 284) as white lyophillate (30 mg, 81%). LCMS: RT=4.51 min [M+H] 645.14 (Phenomenex Luna C18 column, 4.6×50 mm eluting with 10-90% MeOH/H2O over 4 minutes containing 0.1% TFA; 4 mL/min, monitoring at 220 nm).
