合成路线1
该中间体在本合成路线中的序号：(X)The reaction of 1-(2,4-dihydroxyphenyl)-2-(4-hydroxyphenyl)-ethanone (I) with DHP and Ts-OH in ethyl acetate gives the bis-tetrahydropyranyl ether (II), which is condensed with the benzaldehyde (III) by means of piperidine in 2-butanol to yield a mixture of the propenone (IV) and the benzopyranone (V). This mixture, without isolation, is treated with DBU to convert (IV) into (V). The methylation of (V) with MeLi in tert-butyl methyl ether affords the benzopyran-4-ol (VI), which is treated with (S)-(+)-camphorsulfonic acid (VII) to provide the dehydrated benzopyran camphorsulfonate (VIII) as a diastereomeric mixture that is separated by crystallization. The desired isomer (IX) is treated with TEA to give the title compound (X) as free base that is finally treated with HCl in EtOH/water to yield the desired hydrochloride.
