Reaction Steps

A mixture of 1-aminonaphthalene (7.15 g, 50 mmol), 1-bromo-2-methylbenzene (8.5 g, 50 mmol), Pd(dppf)Cl2 (1.0 g, 1.36 mmol), sodium tert-butoxide (9.6 g, 0.1 mol) in toluene (120 mL) was degassed and heated at about 100° C. overnight. The resulting mixture was worked up with ethyl acetate/brine, dried over Na2SO4, loaded on silica gel and purified by flash column using eluents of hexanes to hexanes/dichloromethane 9:1. After removal of solvents, an oil (Compound 20) was obtained, 10.2 g in 91.5% yield.
