Procedure

A small screw cap test tube was charged with 2-tert-Butyl-5-methyl-2H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 50, 70 mg, 0.157 mmol) and THF (2 mL). To the resulting solution was added 5-amino-2-methoxyphenol (26 mg, 0.1868 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature and concentrated in vacuo. The solid residue was recrystallized with ˜5 mL of i-prOH affording the title compound in 71% yield (0.063 g, 0.111 mmol).
