反応手順
The 3-(3,5-difluorophenyl)propanal used in the aldol reaction was prepared from trans-3,5-difluorocinnamic acid by: (1) hydrogenation to 3-(3,5-difluorophenyl)propionic acid (L. Kruse et al J. Med. Chem. 1987, 30, 486-494); (2) formation of Weinreb amide (M. Braun Synthesis 1989, 856); and (3) reduction to aldehyde (D. A. Evans J. Org. Chem. 1993, 58, 2446-2453).
