実験手順

To a solution of tert-butyl (3-{cyclopropyl[3-hydroxy-5-(3-methoxypropyl)benzyl] (cyclopropyl)amino}-2-{4-[2-(2,6-dichloro-4-methylphenoxy)ethoxy]benzyl}-3-oxopropyl)carbamate from Example 70, Step 2 (1 eq.) in toluene (0.1 M) was added 2-pyridin-2-ylethanol (1.2 eq.) and 1,1′-(azodicarbonyl)-dipiperidine (1.2 eq.). The resulting orange solution was deoxygenated before tributylphosphine (1.2 eq.) was added. The now yellow-orange solution was heated at 100° C. for 14 h. The reaction mixture was cooled to RT, diluted with ether, and washed with 1 N aq. NaOH. The aqueous wash was back extracted with ether and the combined organic extracts were dried over MgSO4. Filtration and concentration of the filtrate in vacuo afforded a red oil. Purification of the crude product thus obtained by way of flash chromatography (SiO2, 4:1 (v/v) Hex:EtOAc→EtOAc) afforded the title compound as a pale yellow oil.
