실험 절차

A solution of 2.9 g of N-(4-methoxy-6-methylpyrimidin-2-yl)phenylcarbamate in 10 ml of dioxan is added dropwise at 20°-25° C. to a solution of 2 g of 4-azidophenylsulfonamide and 1.6 ml of 1,5-diazabicyclo(5,4,0)-undec-5-ene in 20 ml of dioxan and the mixture is stirred for 3 hours at the same temperature. The reaction mixture is then taken up in 200 ml of water and the aqueous mixture is then acidified with hydrochloric acid to pH 2. The precipitated product is isolated, washed with ethyl acetate and dried, affording N-(4-azidophenylsulfonyl)-N'-(4-methoxy-6-methylpyrimidin-2-yl)urea in 67% yield in the form of greenish crystals with a melting point of 192° C.
