Reaction Steps

A solution of triethylammonium 3,4-bis(benzyloxy)-5-(dimethylcarbamoyl)-1-(4-methoxyphenyl)-1H-pyrrole-2-carboxylate (7) (3.5 g, 6.70 mmol) in acetic acid (100 mL) was stirred at RT for 4 h and then 110° C. for 1 h. The volatiles were removed in vacuo and the crude material partitioned between EtOAc (100 mL) and 1M NaOH (aq.) (20 mL)/brine (50 mL), the organic layer was then dried (MgSO4), filtered and concentrated in vacuo to afford 3,4-bis(benzyloxy)-1-(4-methoxyphenyl)-N,N-dimethyl-1H-pyrrole-2-carboxamide (9) (3.05 g, 100%) as a yellow oil: m/z 457 (M+H)+ (ES+).
