実験手順
To a stirred suspension of 2.5 g (22.5 mM) of creatinine in 30 ml of anhydrous DMF was added a solution of 2.87 g (18 mM) of 5-chloro-2-thienyl isocyanate in 15 ml of toluene. The resulting mixture was heated at 80° C. for 3.5 hrs., cooled, and poured into a mixture of 250 ml of water and 50 ml of toluene. The precipitate was collected and recrystallized from ethyl acetate to give 1.5 g of the above urea as a tan solid, m.p. 204°-205° C.
