Procedure

A small screw cap test tube was charged with Thiophene-2-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 45, 100 mg, 0.256 mmol) and THF (2 mL). To the resulting solution was added 3-aminophenol (34 mg, 0.3116 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 84% yield (0.104 g, 0.2159 mmol).
