Procedure
A mixture of 3-(4-bromo-2-chloro-phenyl)-1,1,1-trifluoro-2-(2-methyl-pyridin-4-yl)-butan-2-ol (10 mg), Pd(PPh3)4 (3 mg), Cs2CO3 (24 mg) and 4-carboxybenzeneboronic acid (CAS Reg. No. 14047-29-1, 8 mg) in dioxane (2 ml) was heated for 30 min at 160° C. in a microwave oven. The mixture was purified by prep. HPLC (C18-column, solvent gradient 30-98% CH3CN in 0.1% HCOOH[aq]) to give the title compound (3 mg) as a light yellow solid. MS (m/e)=450.1 [M+H+].
