Procedure

To a solution of the compound prepared in Example 344 (50 g) in ethanol (250 mL) was added ethyl 2-chloroacetoacetate (42 mL) at room temperature. The mixture was heated to reflux for 12 hours, cooled and concentrated. The residue was stirred with hexane (250 mL) for 30 minutes, filtered and then washed with hexane (50 mL). The solid was dried to obtain the title compound (48.6 g) having the following physical data.
