An ambient temperature continuous flow method for nucleophilic amidation and thioamidation is described. Deprotonation of formamides by lithium diisopropylamine (LDA) affords carbamoyllithium intermediates that are quenched in situ with various electrophiles such as ketones, allyl bromides, Weinreb and morpholino amides. The nature of the reactive lithium intermediates and the thermodynamics of the

-receptor ligands, wherein A is a cyclic amine which is linked to the propylene group via an amino nitrogen; B is selected from the group consisting of heteroaryl, 5-8-membered heterocycloalkyl, 5-8-membered cycloalkyl; X is either N or CH; Y is either O or S.
New ligands for the ORL-1 receptor are described, useful for antagonising the activity of said receptors in a patient in need thereof, and for preventing and treating illnesses dependent on the activation of this receptor. The new compounds conform to structural formula (I) wherein R1, R2, R3, R4 are further defined in the description.
