To 7-methoxy-1,1-dimethyl-3,4-dihydro-1H-naphthalen-2-one (Compound A2, 924 mg), 4-iodo-3-methoxymethoxy-pyridine (1 g), sodium t-butoxide (906 mg), Pd2dba3 (173 mg) and S-Phos (185 mg), toluene (19 ml) was added, and the mixture was stirred and heated at 70° C. for 2 hrs under nitrogen atmosphere. The reaction mixture was diluted with ethyl acetate and filtered through Celite. 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 (610 mg, 47%).
