Reaction Steps
A solution of commercially available 3,4,5-trifluoro-nitrobenzene (25b) (5.0 mL, 42.8 mmol), diethyl methylmalonate (6.1 mL, 35.7 mmol), and sodium hydroxide (1.54 g, 38.5 mmol) in DMF (55 mL) was allowed to react in the same manner as in (a) in Production Example 1. The crude product was subjected to silica gel column chromatography and elution with an n-hexane/ethyl acetate (10:1) solution to give 9.1 g (63%) of compound (26b) of interest as clear brown oil.
