실험 절차

In one more aspect, the present invention relates to pyrrolo[b]cyclohexanone, the intermediate of Formula (II), which is synthesized by the route outlined below: 6-amino-5-oxohexanoic acid hydrochloride(S1) and ethyl acetoacetate were refluxed in a.q. sodium dihydrogen phosphate to generate substituted pyrrole(S2). Then the compound S2 was solved in polyphosphoric acid (PPA), P2O5 used as dehydrant, reacted to generate ethyl 2-methyl-7-oxo-4,5,6,7-tetrahydro-1H-indole-3-carboxylate (S3) at 70° C. 2-methyl-7-oxo-4,5,6,7-tetrahydro-1H-indole-3-carboxylic acid (S4) is obtained by the hydrolysis of (S3) in 1 mol/L a.q. LiOH. Finally, S4 is reacted with H—R6 at room temperature for 24 hours in DMF to give pyrrolo[b]cyclohexanone of Formula (II) by using a condensation reagent.
