Procedure
To a solution of methyl 2,6-dichloronicotinate (CAS Reg. No. 65515-28-8, 20 mg) in DMF (0.5 ml) was added 5-[2-(2-chloro-4-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-1,3-dimethyl-1,3-dihydro-benzoimidazol-2-one (Example 85, 40 mg), followed by triethyl amine (0.02 ml). The mixture was stirred for 10 min, then DABCO (2 mg) was added. The mixture was stirred at room temperature over night. Water was added to the mixture and extracted with EtOAc. The combined organic layers were dried over Na2SO4 and concentrated to an oil. The residue was purified by flash chromatography (SiO2, 1:2 EtOAc/heptane) to give the title compound (55 mg) as white foam. MS (m/e)=585.9 [M+H+].
