Reaction Steps
A mixture of 3.0 g (12.8 mM) of the phenyl carbamate 8 and 1.8 g (12.8 mM) of 2-amino-5-nitropyridine in 20 ml of anhydrous DMF was stirred at 25° C. for 2 days. The reaction mixture was filtered and the collected solid washed successively with cold DMF, ethyl acetate, and ether to give 1.0 g of the above urea as yellow solid, m.p. 225°-227° C. (dec.).
