Participants

Reaction Steps

To a solution of EXAMPLE 101B (3.89 g) in acetonitrile (20 ml) was added Pd(PhCN)2Cl2 (38 mg), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (143 mg), and Cs2CO3 (3.91 g). The mixture was purged with argon and stirred at room temperature for 25 minutes. After this time, 1-(prop-2-ynyloxy)naphthalene (2.2 g) was added to the mixture which was purged with argon again. The mixture was then stirred at 80° C. for 3 hours. The mixture was diluted with ethyl acetate (300 ml) and washed with water, brine and dried over Na2SO4. After filtration, the solvent was concentrated and the residue was loaded on a silica gel column and eluted with 5% ethyl acetate in hexane to give EXAMPLE 102A.
