A metal-free and concise method for the selective synthesis of primary amines directly from 2-(1-tosylalkyl)phenols with aqueous ammonia under mild conditions has been developed. In addition, primary amine could be conveniently converted to benzoxazinone in good yield. (C) 2015 Elsevier Ltd. All rights reserved.
