Procedure
A solution of 8-methoxy-2,9-dimethyl-1-oxo-1,2,3,4-tetrahydro-β-carboline-5-carboxylic acid (from step 5) (1 mmol), p-nitrophenol (1.5 mmol), EDCl (1.5 mmol) and DMAP (0.1 mmol) in dry THF was stirred at r.t. for 18 h. Minimum water was then added and the precipitated p-nitrophenylester was filtered and washed with water and dried (50-60%).
Workup
- filtrationthe precipitated p-nitrophenylester was filtered
