Reaction Steps
A mixture of 3-[(1-ethylpropyl)amino]-6-methyl-2,4-dinitrobenzyl alcohol (1.0 g; 0.0033 mol), methyl isocyanate (used in excess over theory), triethylamine (1 drop) and benzene (10 ml) is refluxed for 2 hours. The precipitated solid is collected to afford 1.1 g (91.6%) title product, melting point 117°-120° C.
