Methane → 2-Cyanomethoxy-5-(1,1-dimethylethyl)benzenamine

Participants

Reaction Steps

2-Amino-4-(1,1dimethylethyl)phenol (90.0 g, 546 mol, described in Example 1) was dissolved in acetone (900 ml) and heated at reflux for 2 days in the presence of anhydrous potassium carbonate (81.0 g, 534 mmol) and chloroacetonitrile (40.5 g, 535 mmol). The mixture was allowed to stand for an additional day at 20°-24° C. The mixture then was treated with more potassium carbonate (15.0 g) and chloroacetonitrile (10 g) under the same conditions. The mixture was mixed with charcoal and filtered through diatomaceous earth. The filtrate was evaporated to afford a residue which, when dissolved in hexane containing a small amount of ethyl acetate, afforded tan crystals of the title compound; Anal.
