Aldehyde (XVII) was further oxidized to carboxylic acid (XVIII) using sodium chlorite. Conversion of acid (XVIII) into the methyl ester (XIX) was effected by treatment with iodomethane and K2CO3. Finally, the two-step reduction of the carbonyl group of (XIX) with NaBH4 followed by HI/Ac2O, proceeded with concomitant ester hydrolysis, yielding the title compound.
