Significance

Anacetrapib inhibits cholesteryl ester transfer protein (CETP), a plasma glycoprotein that transfers cholesteryl ester from high density ­lipoprotein to low density lipoprotein and very low density lipoprotein, consequently lowering the risk of atherosclerosis. Key steps in the synthesis depicted are (1) a highly regioselective SNAr reaction of 1-bromo-2,4-fluorobenzene (A) with potassium methoxide (rr =17:1) and (2) a multi-kilogram scale ruthenium-catalyzed direct arylation of oxazoline F to construct the biaryl G.
