反応手順
To a solution of 4-nitro-3-isopropoxy-ethylbenzoate (11.85 g, 0.047 mol) in ethanol (200 mL) was added a solution of potassium hydroxide (2.6 g, 0.047 mol) in water (5 mL). The reaction mixture was heated to reflux for 2 hours. The ethanol volume was reduced to 100 mL and the mixture then poured into 1 N HCl (100 mL). The crystals that precipitated, were filtered off and dried in a vacuum oven to yield 9.35 g (88%) of 4-nitro-3-isopropoxybenzoic acid. MS ES− 225, ES+ 223.
