Procedure
Tert-butyl hypochlorite (5.92 g, 0.0545 mol) is added to a solution of methyl 2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)nicotinate (10.0 g, 0.0363 mol) and methanol. The reaction mixture is covered with foil and stirring is continued for 1 day. The reaction mixture is concentrated in vacuo to give a liquid. The liquid is dissolved into methylene chloride, dried over anhydrous magnesium sulfate and concentrated in vacuo to yield a yellow syrup. The yellow syrup is chromatographed using silica gel and 5% ethyl acetate in hexanes as eluent to give the title compound as a colorless syrup (7.16 g, 64%), identified by IR and NMR spectral analyses.
