実験手順
To a suspension of (tetrahydro-2-oxo-1(2H)-pyrimidinyl)carbamic acid, phenylmethyl ester (35.5 g, 135.9 mmol) in 500 ml ethyl acetate, chlorosulfonyl isocyanate (24.0 g, 169.9 mmol) was added. The resulting solution was stirred for one hour and hydrolyzed by adding 175 ml water. The phases were separated, the organic phase washed with water and brine and dried over magnesium sulfate. Evaporation of the solvent and trituration of the residue with ether yielded 38.0 g of the desired product, melting point 135.6° C.
