Reaction Steps

A mixture of 5.0 g (21.4 mM) of the phenyl carbamate 8 and 1.2 g (10.7 mM) of 2-amino-3-methyl-pyridine in 25 ml of anhydrous DMF was heated at 55° for 3 hrs. and then cooled. The solid was collected via filtration and washed successively with cold DMF, ethyl acetate and ether. Recrystallization from ethanol and a final wash with water gave 0.07 g of the above urea as a pale yellow solid, m.p. 219°-221° C. (dec.).
