Reaction Steps

To a solution of EXAMPLE 101B (388 mg) and 2-(naphthalen-1-yloxy)ethanol (188 mg) in toluene (3 ml) was added 1,1′-binaphthyl-2-yldi-tert-butylphosphine (7.5 mg), palladium(II) acetate (5 mg) and Cs2CO3 (488 mg). The mixture was purged with argon and stirred at room temperature and then heated at 80° C. overnight. After this time the mixture was diluted with ethyl acetate (200 mL) and washed with water, brine and dried over Na2SO4. After concentration of the solvent, the residue was loaded on a silica gel column and eluted with 5% ethyl acetate in hexane to give EXAMPLE 101C.
