実験手順
A mixture of 21.5 grams (0.1 mole) 3'-chloro-4'-hydroxy-5'-nitroacetophenone and 85.0 milliliters (a large excess) of methylisocyanate was refluxed for 5 hours. On cooling, a white crystalline product was formed. The product was filtered (weight 18.0 grams, melting point 115°-118° C.) and was identified by characteristic peaks in the infrared spectrum as 3'-chloro-4'-(N-methylcarbamoyloxy)-5'-nitroacetophenone.
