HCID 86654110(cis-2,3,4a,5,6,10b-Hexahydro-1H-benzo[f]quinolin-4-yl)-(3-hydroxy-4-methyl-phenyl)-methanoneYield 77%

Procedure

The title compound is prepared from 3-hydroxy-4-methyl-benzoic 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: 77% of theory; LC (method 4): tR=2.00 min; Mass spectrum (ESI+): m/z=322 [M+H]+.
