Procedure

To a solution of N-benzyl-1-methoxy-N-((trimethylsilyl)methyl)methanamine (56.6 g, 0.24 mol) in dry CH2Cl2 (160 ml) was added (E)-3,3-difluoro-1-nitroprop-1-ene (25 g, 0.2 mmol) and a few drops of TFA at 0° C. The resulting mixture was stirred at rt overnight. The mixture was concentrated and purified by flash column chromatography (petroleum ether:EtOAc=100:1 to 25:1) to give the title compound (25 g, 49% yield) as a yellow oil.
