Reaction Conditions

Reaction Steps

A solution of tert-butylisocyanate (1.17 g, 0.012 mol) in dry N-methyl-2-pyrrolidone (NMP) (50 mL) was added slowly to a solution of trans-1-(4-aminocyclohexyl)-3-cyclohexylurea (2.83 g, 0.012 mol) in dry NMP (100 mL) under inert atmosphere. The resulting mixture was heated to 70° C. and stirred for 24 h. The solution was precipitated in 1 M HCl and filtered off. The resulting white solid was washed with THF, recrystallized from DMF and dried under high vacuum.
