HCID 86654127(cis-2,3,4a,5,6,10b-Hexahydro-1H-benzo[f]quinolin-4-yl)-imidazo[1,2-a]pyridin-7-yl-methanoneYield 95%

Procedure

The title compound is prepared from imidazo[1,2-a]pyridine-7-carboxylic acid and cis-1,2,3,4,4a,5,6,10b-octahydro-benzo[f]quinoline following a procedure analogous to that described in Example 1 [2-(7-aza-1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexa-fluorophosphate is used]. Yield: 95% of theory; LC (method 4): tR=1.59 min; Mass spectrum (ESI+): m/z=332 [M+H]+.
