実験手順
A solution of 6-fluoro-2,2-dimethyl-chroman-4-one (EP 193493; 1 equiv.) in ethanol (0.24 M) was treated with copper chromite (0.6 equiv.). The reaction was heated to 200° C. for 6 hours at 3000 psi of hydrogen gas. The reaction was filtered and concentrated to a solid. The crude material was recrystallized form hot hexanes to give the title compound. MS found 198 [M+H]+
