Toluene (0.5 ml) was added to 7-methoxy-1,1-dimethyl-3,4-dihydro-1H-naphthalen-2-one (Compound A2, 36 mg), 2-iodo-3-(4-methoxy-benzyloxy)-pyridine (Compound GT15-1, 50 mg), sodium t-butoxide (35.3 mg), Pd2dba3 (13.5 mg) and Xantphos (17 mg), and the mixture was stirred and heated at 80° C. for 2.5 hrs under nitrogen atmosphere. After cooling, the reaction mixture was diluted with ethyl acetate and subjected to Celite filtration. The organic layer was washed with saturated aqueous solution of sodium bicarbonate and saturated brine, and then concentrated under reduced pressure. The resulting residues were purified by silica gel column (ethyl acetate/hexane) to obtain the title compound (27 mg, 44%).
