Prakash, Anjanappa published the artcileEfficient indoles and anilines syntheses employing tert-butyl sulfinamide as ammonia surrogate, Application of 5-Aminopyrimidine-2-carbonitrile, the publication is Tetrahedron Letters (2011), 52(43), 5625-5628, database is CAplus.
Tert-Bu sulfinamide is an ammonia equivalent for the palladium-catalyzed amination of aryl bromides and aryl chlorides. Using these amine derivatives, it has been observed that substituted indoles and anilines with sensitive functional groups can be readily prepared This surrogate has also been used for the synthesis of indoles from (2-bromophenyl)ethynes using palladium-catalyzed cross coupling reaction as the key step.
