Versuchsvorschrift

1 mole of 2-methylindoline is dissolved in 300 ml of toluene and 1 mole of methyl isocyanate is added, the temperature not rising above 25° C. The mixture is left to stand for 1 day and the resulting precipitate is then filtered off. N-Methylaminocarbonyl-2-methylindoline with a melting point of 158°-160° C. is obtained.
