An Efficient Metal-Free Mono N-Alkylation of Anilines via Reductive Amination Using Hydrosilanes

2-Aminoquinazolin-4-one based efficient organocatalytic eco-friendly reductive amination approach was developed for the mono N-alkylation of anilines using hydrosilane as a reducing agent. This practically easy and sustainable approach works under neat reaction conditions and utilizes non-toxic environmentally benign acetic acid as a dehydrating agent. The developed protocol have several advantages, such as broad substrate scope, wide functional group tolerance, short reaction time, and absence of metal catalyst in the reaction.
