To solution of (2-{3-[6-(1-Methanesulfonyl-1-methyl-ethyl)-quinolin-8-yl]-benzyloxy}-phenyl)-phenyl-methanone (EXAMPLE 74) (1.0 eq) in THF (0.03M) was added CeCl3 (2.7 eq). The resulting mixture was stirred for 1 h, then cooled to −78° C. Cyclopropyl magnesium bromide (0.24M in THF; 4.8 eq) was added and the final mixture was allowed to warm-up to room temperature. After stirring for 1 h the mixture was poured in saturated aqueous NH4Cl and extracted with EtOAc (2×). The combined organic extracts were washed with brine, dried over MgSO4, filtered and concentrated. Flash chromatography (Hex:EtOAc; 40 to 100% in 15 min) afforded the title compound as a foam.
