الإجراء التجريبي

A small screw cap test tube was charged with 2-Ethyl-5-methyl-2H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-5-carbonyl)-phenyl]-amide (as prepared in Example 1, 30 mg, 0.072 mmol) and THF (1 mL). To the resulting solution was added 4-aminophenylacetic acid (16.4 mg, 0.1082 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature. Hexanes were added to the reaction mixture. The solid precipitate that formed was washed with ˜1 mL of ice cold THF yielding 42% (16.7 mg, 0.030 mmol) of the title compound.
