Versuchsvorschrift

(tert-Butoxy)-N-(4-fluoro-3-methoxyphenyl)carboxamide (0.98 g, 4.06 mmol) (from Example 34c supra) was treated with 4 N hydrochloric acid in dioxane (20 mL) (Aldrich) overnight at room temperature. The resulting precipitate was collected by filtration and washed with dry ether to give 4-fluoro-3-methoxyphenylamine hydrochloric acid salt as a white, crystalline, solid. (Yield 512 mg, 71%).
