Ethyl 2,4-di-0-methyl-3-chloroorsellinate5 Ethyl 2,4-dimethoxy-3-chloro-6-methylbenzoate (2,4-Di-0-methyl-3-chlororsellinsaureethylester, 2,4-Dimethoxy-3-chlor-6 methylbenzoesaureethylester)... [Pg.421]

Preparation by hydrogenolysis of 4,6, 6 -tris-(benzyloxy)-3,3 -dichloro-2, 4 -dimethoxy-2-methyl-benzophenone (SM) in ethyl acetate/tetrahydrofuran in the presence of 10% Pd/C at 25° (29%). SM was obtained by condensation of 4,6-bis(benzyloxy)-3-chloro-2-methylbenzoic acid with 4-chloro-3,5-dime-thoxyphenol benzyl ether in the presence of trifluoroacetic anhydride in methylene chloride under nitrogen for 20 min [1179]. m.p. 217-219° [1179] H NMR [1179], IR [1179], MS [1179].
