실험 절차

Using the method of Swern, et al., 100 mg of N-(2-{[4-(2,4-dichlorophenyl)-5-(hydroxymethyl)pyrimidin-2-yl]amino}ethyl)(tert-butoxy)carboxamide was dissolved in 1 mL of anhydrous methylene chloride and added to a solution of oxalyl chloride (30.7 μL, 0.363 mmol) and DMSO (51.6 μL, 0.726 mmol) which had been stirring at −78° C. for 15 min. The resulting solution was stirred for an additional 30 min, at which time 202 μL (1.45 mmol) of triethyl amine was added. The resulting suspension was allowed to warm to room temperature after 15 min and 1 mL of water was added and the layers separated. The aqueous layer was extracted with methylene chloride and the combined organic layers dried (sodium sulfate) and concentrated to afford N-(2-{[4-(2,4-dichlorophenyl)-5-formylpyrimidin-2-yl]amino}ethyl)(tert-butoxy)carboxamide as a light yellow foam. This product proved to be air sensitive and was used without further manipulation.
