Participants

Reaction Steps

Synthesized from 6-benzyloxy-3,4-dihydro-2H-naphthalen-1-one according to an analogous synthetic method to Preparation Example 91, 2-benzyloxy-5,7,8,9-tetrahydrobenzocyclohepten-6-one (7.2 g) was used according to an analogous synthetic method to Preparation Example 82 to provide 2-benzyloxy-8,9-dihydro-7H-benzocyclohepten-6-yl trifluoromethanesulfonate (6.7 g). Synthesized from this compound and tributyl(4-methoxy-2-nitrophenyl)tin according to an analogous synthetic method to Preparation Example 77, 3-benzyloxy-8-(4-methoxy-2-nitrophenyl)-6,7-dihydro-5H-benzocycloheptene (4.7 g) was used according to an analogous synthetic method to Example 30 to provide the title compound (2.4 g).
