Versuchsvorschrift

A solution of 2-hydroxy-α,α-dimethyl-benzeneacetamide (Example 198b, 15.34 g) dissolved in DMF (150 mL) was treated with potassium carbonate (11.83 g) and benzyl bromide (10.18 mL) under nitrogen. The resulting mixture was stirred at 25° C. for 16 h. The reaction mixture was diluted with water (500 mL) and stirred for 30 min. The solid was filtered off and washed with water and dried in vacuo to afford the subtitle compound (19.45 g).
