実験手順

To an anhydrous solution of 2.3 g of m-isocyanatobenzenesulfonyl isocyanate in 50 ml of methylene chloride was added in small portions 1.4 g of 2-amino-4-methoxy-6-methylpyrimidine. Efficient stirring was maintained during the addition and for three additional hours. The intermediate thus obtained, 3-isocyanato-N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]benzenesulfonamide, was reacted further by adding one gram of 2-propanol and stirring the resultant mixture for an additional sixteen hours. Filtration of the reaction mixture and evaporation of the filtrate yielded the desired product melting at 173°-180°.
