Participants

Reaction Steps

9.15 g. (0.05 M) of 2-benzoxazolinylidene-malononitrile and 16.0 g. (0.4 M) of sodium hydroxide are dissolved in 500 ml. of water. The solution is brought to 5° C. while stirring and, over a period of 1 hour, 25.2 g. (0.2 M) of dimethyl sulfate are added dropwise. The resulting crystals are filtered off under suction, washed with water and dried to obtain 3-methyl-benzoxazolinylidene-malononitrile of melting point 198°-200° C.
