  A general and cost-effective route has been developed to synthesize 1-heteroarylsubstituted cycloalkylamines from readily available heteroarylacetate in good yields. This synthesis features a LHMDS promoted cyclization and one-pot hydrolysis/Curtius rearrangement. This route can be easily carried out on multi-gram scale and be also used to prepare 1-arylsubstituted cycloalkyl/cycloheteroalkylamines
