Reaction Conditions

Reaction Steps

To a cold (0° C.) solution of 1,3-dimethyl-2-imidazolidinone oxime (prepared according Kitamura, Mitsuru; Chiba, Shunsuke; Narasaka, Koichi, Bulletin of the Chemical Society of Japan (2003), 76(5), 1063-1070) (5.3 g, 0.041 mol) in dry pyridine (25 ml) within 15 minutes is dropwise added cyanuric fluoride (1.49 g, 0.011 mol). The mixture is then heated for 2 h at 42° C. and then stirred for 15 h at room temperature. The pyridine is evaporated under reduced pressure, the residue is chromatographed (silica gel, CH2Cl2—CH3OH 20:1 to 10:1) and the pure fractions are crystallized from ethyl acetate hexane to afford 2.4 g of the title compound as white crystalls, mp. 143-145° C. (decomposition).
