Reaction Steps

In a manner similar to the method described in example 52a, 1,2-difluoro-4-isopropoxy-benzene (5.77 g, 33.5 mmol) prepared in example 62a was reacted with lithium diisopropyl amine (20.5 mL, 1.8 M in THF, 36.9 mmol), N,N-dimethyl-formamide (3.11 mL, 40.2 mmol) and quenched with acetic acid (8.0 g, 134 mmol) in tetrahydrofuran to give 2,3-difluoro-6-isopropoxy-benzaldehyde as a white crystal (Yield: 6.02 g, 89.9%).
