Procedure

To a solution of 40.0 g (94.16 mmol) diethyl 2-acetylamino-2-(4-amino-3-chloro-5-trifluoromethyl-benzyl)-malonate (Intermediate product 56) in 110 mL AcOH and 150 mL water was added 50 mL conc. aqueous HCl and the reaction mixture was heated to 140° C. for 4 hours. The precipitate formed was filtered off and discarded. The filtrate was evaporated i. vac., combined with 100 mL EtOH and stirred for 15 minutes at RT. The precipitate formed was filtered off, washed with EtOH and dried i. vac. The crude product was used in the next reaction step without any further purification.
