실험 절차
0.88 g (0.005 mol) of 2-amino-4-methoxypteridine were suspended in 40 ml of methylene chloride and 1.2 g (0.0055 mol) of 2-fluorophenoxysulfonyl isocyanate were added thereto rapidly to obtain a clear solution. The solution was heated to reflux for a short time, thereafter stirred for 10 minutes and then was concentrated by evaporation to dryness. The residue was treated with diisopropyl ether and a little acetone and the mixture was vacuum filtered. The product was dried to obtain 1.95 of N-(4-methoxypteridin-2-yl)-N'-(2-fluorophenoxysulfonyl)-urea in the form of light yellow crystals melting at 135° C.
