Procedure

The compound obtained in Step A is dissolved in DMF and 2 equivalents of potassium carbonate are added. After stirring for 20 minutes at 80° C., 1.2 equivalents of dimethyl 2-[4-(2-chloroethoxy)benzylidene]malonate are added and the reaction is heated for 12 hours. The reaction mixture is then hydrolysed in water and filtered, and the resulting precipitate is recrystallised from methanol to yield the title product.
