実験手順
To a stirred suspension of 3.0 g (26.0 mM) of creatinine in 50 ml of anhydrous DMF was added dropwise a solution of 3.7 g (26 mM) of 3-methyl-2-thienyl isocyanate in 35 ml of toluene. After stirring at 90° C. for 6 hrs., the reaction mixture was cooled and poured into 100 ml of water. The separated solid was collected, washed with water and recrystallized from ethyl acetate to give 1.2 g of the above urea as a grey-white solid, m.p. 201°-202° C.
