Reaction of 2‐(2‐bromophenyl)‐2‐methyl‐1,3‐dioxolane with lithium (1,1‐dimethylethyl)amide, lithium (2,2‐dimethylpropyl)amide, lithium (1,1‐dimethylpropyl)amide gave the corresponding N ‐(alkyl)‐3‐(2‐methyl‐1,3‐dioxolan‐2‐yl)benzenamines in moderate yields. 1‐[3‐[(1,1‐Dimethylethyl)amino]phenyl]ethanone ( 4 ) was prepared in over 80% yield from 2‐(2‐bromophenyl)‐2‐methyl‐1,3‐dioxolane ( 2 ).
