Reaction Steps

A small screw cap test tube was charged with 2,5-Dimethyl-2H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 60, 132.3 mg, 0.3288 mmol) and THF (2 mL). To the resulting solution was added 1-(4-Amino-phenoxy)-3-diethylamino-propan-2-ol (prepared below; 95.7 mg, 0.4015 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature. The room temperature reaction mixture was concentrated in vacuo. The solid residue was recrystallized from EtOAc (5 mL) and Hexanes (2 mL) yielding the title compound in 35% yield (0.072 g, 0.1156 mmol).
