Reaction Steps

In a manner similar to the method described in example 52a, 1,2-difluoro-4-propoxy-benzene (17 g, 98.8 mmol) prepared in example 104a was reacted with lithium diisopropyl amine (59.2 mL, 2.0 M in THF, 0.118 mmol), N,N-dimethyl-formamide (9.17 mL, 0.118 mol) and quenched with acetic acid (23.7 g, 0.395 mol) and water (41.2 mL) in tetrahydrofuran to give 2,3-difluoro-6-propoxy-benzaldehyde as a yellow solid (Yield: 8.2 g, 42%).
