Participants

Reaction Steps

242 mg (0.59 mM) of the product of step 2, 1,1-dimethylethyl ester of 1-(hydroxymethyl)-1,6-dihydro-8-methyl-5-(phenylmethoxy)-benzo[1,2-b:4,3-b']dipyrrole-3(2H)-carboxylic acid, is dissolved in distilled THF (2.4 ml) and absolute ethanol (25 ml). The compound is hydrogenalized over 10% palladium on carbon (192 mg) at 42 PSI for 50 minutes. The reaction is filtered through diatomaceous earth, washing with absolute ethanol. Evaporation yields compound 4, 1,1-dimethylethyl ester of 1-(hydroxymethyl)-1,6-dihydro-8-methyl-5-hydroxy-benzo[1,2-b:4,3-b']dipyrrole-3(2H)-carboxylic acid.
