実験手順
The title compound was prepared in analogy to Example 196 from 5-[2-(2-chloro-4-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-3-methyl-3H-benzooxazol-2-one (obtained in Example 172) by alkylation with methyl-6-chloropyridazine-3-carboxylate [CAS Reg. No. 65202-50-8]. MS (m/e)=538.2 [M+H+].
