Procedure

The compounds described in the following Table 43 were synthesized according to the method shown below. According to the method used for the preparation of Compound Z10, Z11 and Z12, 3-chloro-8-methoxy-6H-benzo[b]naphtho[2,3-d]furan-11-one was prepared from Compound A2 and 2-bromo-5-chlorophenol. Subsequently, demethylation was carried out according to the method that is used for the preparation of Compound A6, and thus 3-chloro-8-hydroxy-6H-benzo[b]naphtho[2,3-d]furan-11-one was obtained. Thereafter, according to Mitsunobu reaction that is used for the preparation of Compound A7-1 or the alkylation method that is used for the preparation of A7-17, a corresponding side chain was introduced and, if necessary, functional group modification such as deprotection, etc. was carried out to prepare the compounds listed below.
