Aniline → Hydrochloric Acid

Participants

Reaction Steps

In a similar manner N-(3-((((4R,4aS,6R,7R,7aR,12bS)-3-(cyclopropylmethyl)-9-hydroxy-7-methoxy-1,2,3,4,5,6,7,7a-octahydro-4a,7-ethano-4,12-methanobenzofuro[3,2-e]isoquinolin-6-yl)methoxy)methyl)phenyl)acetamide (Compound 72) was prepared from R-101 using 3-bromobenzyl bromide, followed by conversion of the aryl bromide to the aniline, subsequent reaction of the aniline with acetyl chloride and final cleavage of the p-methoxybenzyl group by TFA. Purification by flash column chromatography (silica gel, 0-10% MeOH/DCM) followed by HCl salt formation gave Compound 72 HCl salt as a white solid.
