Procedure

To a solution of (4-chloro-3-(trifluoromethyl)phenoxy)benzaldehyde (1.82 g, 6.0 mmol) and dimethyl(1-diazo-2-oxopropyl)phosphonate (2.3 g, 12.1 mmol) in methanol (30 mL), was added potassium carbonate (4.18 g, 30.3 mmol), and stirred for 1 h at rt. The reaction mixture was concentrated and the residue was purified by FC (PE/EtOAc 20:1) to afford the title compound as a colorless oil.
