Reaction Steps

A mixture of 1-ethoxy-2,2-difluoroethanol (60 g, 0.47 mol), CH3NO2 (32.9 g, 0.56 mol) and Na2CO3 (3 g) was stirred at 60° C. for 3 hrs, then at rt overnight. The mixture was diluted with water (40 mL), extracted with tert-butyl methyl ether (200 mL) and the organic layer was dried over Na2SO4 and concentrated under low temperature to give the title compound, which was used for next step directly.
