Cesium fluoride → 2-[2'-(3-Methoxypropyl)-3-methylbiphenyl-4-yl]-3-pyridin-3-ylpropanenitrile

Participants

Reaction Steps

To a solution 2-(4-bromo-2-methylphenyl)-3-pyridin-3-ylpropanenitrile (1 eq.) from step 1 and [2-(3-methoxypropyl)phenyl]boronic acid from EXAMPLE 3, step 1 (1.2 eq.) in DME (0.1M) at room temperature was added palladium tetrakistriphenyl phosphine (Pd(PPh3)4; 0.05 eq.) and CsF (2.4 eq.). The mixture was refluxed for 2 h, cooled to room temperature, poured in water and extracted with EtOAc. The organic extract was washed with water, brine, dried over Na2SO4 filtered and concentrated. Purification by column chromatography on silica gel (Combi-Flash by ISCO), eluting with Hex/EtOAc (0 to 65% in 30 min) afforded the desired compound.
