Reaction Steps

A mixture of [2-methyl-2-(2-methyl-1-pyrrolidinyl)-1-phenylpropyl]amine D26 (0.150 g; 0.647 mmol), 2-chloro-3-(trifluoromethyl)benzoic acid (0.174 g; 0.775 mmol), EDC (0.149 g; 0.777 mmol) and HOBt (0.020 g; 0.148 mmol) in DCM (4 ml) was shaken at room temperature for 66 hours. Saturated sodium hydrogen carbonate (8 ml) was added and shaking continued for 0.5 hours. The organic layer was passed through a phase separation cartridge and applied to a 2 g SCX column. The column was washed with DCM and methanol and the product eluted with 1M ammonia in methanol. The crude product was purified by chromatography on silica gel (20 g) eluting with 0-100% ethyl acetate in pentane gradient to afford the title compound as two pairs of enantiomers.
