Versuchsvorschrift

To a suspension of 2-(2,5-Dichloro-pyrimidin-4-ylamino)-3-fluoro-phenol (0.150 g, 0.547 mmol), 2-(Tetrahydro-pyran-2-yloxy)-ethanol (0.0960 g, 0.657 mmol), and Triphenylphosphine (0.230 g, 0.876 mmol) in Methylene chloride (6 mL) cooled to 0° C. on an ice bath was slowly added Di-tert-butyl azodicarboxylate (0.202 g, 0.876 mmol), at which time a solution formed. The reaction mixture was stirred at rt overnight. The reaction did not go to completion so equal amounts of 2-(Tetrahydro-pyran-2-yloxy)-ethanol, Triphenylphosphine, Methylene chloride, and Di-tert-butyl azodicarboxylate were added as were at the start of the reaction and stirred. The reaction mixture was then concentrated and dissolved in minimal amounts of DCM. It was then purified by silica gel chromatography (ISCO, 0-30% EtOAc) to give (2,5-Dichloro-pyrimidin-4-yl)-{2-fluoro-6-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-phenyl}-amine as a clear oil (98 mg, 44%). 1H-NMR (CDCl3): 8.17 (s, 1H), 7.22 (m, 1H), 6.93 (s, 1H), 6.82 (m, 2H), 4.63 (s, 1H), 4.22 (m, 2H), 3.98 (m, 1H), 3.74 (m, 2H), 3.47 (m, 1H), 1.67 (m, 2H), 1.55 (m, 2H) 1.49 (m, 2H)
