Procedimiento

A small screw cap test tube was charged with Thiophene-2-carboxylic acid [4-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 20, 100 mg, 0.257 mmol) and THF (2 mL). To the resulting solution was added 5-amino-2-methoxyphenol (39.2 mg, 0.282 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 57% (75 mg, 0.147 mmol) of the title compound.
