Versuchsvorschrift
One proceeds as described in Example 6 with the difference that a distillating column is attached to the flask, the mixture is maintained in gentle boiling and methanol is removed continuously from the mixture. After 2 hours of reaction the end-product is filtered off, 50 mmoles of methyl N-(4-nitrophenyl)-carbamate and 50 mmoles of 4-nitroaniline are added to the filtrate, and the reaction is repeated. The results of four subsequent cycles are summarized in Table 2.
