PROCEDURE

实验过程

To a solution of (3R,4S)-1-(tert-butoxycarbonyl)-4-{4-[2-(2,6-dichloro-4-methylphenoxy)ethoxy]phenyl}piperidine-3-carboxylic acid (piperidine acid 1) (1 eq) and N-[3-{[tert-Butyl(dimethyl)silyl]oxy}-5-(3-methoxypropyl)benzyl]cyclo-propanamine (amine 1) (1.8 eq.) in DCM (0.15 M) was added HATU (1.5 eq.) and Hunig's base (3 eq.). After stirring for 18 hr at rt, the reaction was diluted with ether. The organic extract was washed three times with 1 N aqueous HCl, water, brine, dried over MgSO4, and concentrated in vacuo. The crude product was purified by flash column chromatography (SiO2, 20% EtOAc in Hex) to afford the title compound as an oil.
