The reaction was stirred at room temperature for 2.5 hours, and then the solvent was removed in vacuo. Water was added to the residue, and the mixture was extracted with ethyl acetate. The organics were dried (Na2SO4) and evaporated to provide 1-(2,6-dichloro-5-fluoro-4-pyrimidinyl)-3-methyl-3-pyrrolidinol as an orange solid (0.486 g, 77%). LCMS: (M+H)+=266.1.
