Versuchsvorschrift

In analogy to Example 63A, tert-butyl(3,4,5-trichlorophenyl)carbamate from Example 66A (3.98 g, 13.4 mmol) was reacted with potassium hydroxide (1.77 g, 26.8 mmol). The reaction mixture was heated to 80° C. overnight and subsequently to 90° C. for 3 h. The product was isolated by preparative HPLC to yield 760 mg (20%).
