Reaction Steps

To a solution of 2-phenyl-1,1-bis(3-(trifluoromethoxy)phenyl)ethanamine (20 mg, 0.045 mmol) in THF (6 mL) was added 1M K2CO3 (20 mg in 0.1 mL), followed by 2-methoxyethyl carbonochloridate (0.106 mL, 0.91 mmol). The resulting mixture was stirred at rt for 16 h. The crude product 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 2-methoxyethyl 2-phenyl-1,1-bis(3-(trifluoromethoxy)phenyl)ethylcarbamate (Example 283) as white lyophillate (12 mg, 51% yield). LCMS: RT=4.19 min [M+H] 544.2 (4 min 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.
