Procedure

A small screw cap test tube was charged with 2-tert-Butyl-5-methyl-2H-pyrazole-3-carboxylic acid [4-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 65, 100 mg, 0.225 mmol) and THF (2 mL). To the resulting solution was added 5-amino-2-methoxyphenol (34 mg, 0.25 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 i-prOH yielding 32% (38 mg, 0.071 mmol) of the title compound.
