Alternatively, morpholine (XVIII) was alkylated with 1,4-dichloro-2-butyne (XXXV) in the presence of K2CO3 to afford the propargyl chloride (XXXVI). Displacement of the chloride of (XXXVI) with sodium azide in DMSO gave the propargylic azide (XXXVII). The title triazole was then produced via isomerization and cyclization of azide (XXXVII) upon heating with dimethylamine in a sealed tube.
