Procedure: The preparation of Example 4 is repeated with the exception that 39 g (0.40) mole maleic anhydride is copolymerized with 52 g (0.60 mole) methacrylic acid in the presence of 14 g di-t-butyl peroxide initiator and 945 g diethyl phthalate in a 2000 ml flask, the methacrylic acid is added over a 20-minute period at a polymerization temperature of 150° C., the reaction solution is held at the polymerization temperature for 10 minutes following the methacrylic acid addition, and the copolymer is hydrolyzed by the addition of 420 g water added at a temperature of 120° C. A substantially homogeneous hydrolyzed methacrylate/maleate copolymer is obtained. The preparation of Example 4 added at a temperature of 120° C

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 18.1 g. (0.055 mole) of diethyl {[(1-phenyl-5-pyrazolyl)amino]methylene}malonate and 150 ml of diethyl phthalate was heated at 240-250° for 1 hour. The mixture was chilled and diluted with hexane. Chilling and filtering gave crystals which were washed with hexane and with hexane-ethanol (1:1) to give 11 g. (70%) of off white crystals, m.p. 149-150° C. From a similar small scale run 1.75 g. was recrystallized from 110 ml. of ethanol to give 1.58 g. of off white crystals, m.p. 149-150° C. A mixture of 18.1 g The mixture was chilled Chilling filtering gave crystals which were washed with hexane and with hexane-ethanol (1:1) to give 11 g was recrystallized from 110 ml of ethanol to give 1.58 g
