実験手順

To a suspension of the 4-(4-methylamino-3-nitro-phenoxy)-pyridine-2-carboxylic acid (1 eq) in dry THF, EDC-HCl (1.2 eq), HOAT (1.2 eq), and diisopropylethylamine (3 eq) were added. The suspension was stirred for 10 minutes whereupon 2,2-dimethyl-oxazolidine (1.1 eq) was added and the solution is allowed to stir overnight. The mixture was then diluted with ethyl acetate and washed with water. The aqueous layer was washed with ethyl acetate, the organic layers combined, dried over MgSO4, filtered, and concentrated. LCMS m/z 333.2 (MH+), tR=2.1 min.
