title: Bile acids. OV. 2,2-Dimethoxypropane: an esterifying agent preferred to diazomethane for chenodeoxycholic acid.
abstract: Artifacts formed by methylation of chenodeoxycholic acid with diazomethane are identical to the synthetic 3alpha- and 7 alpha-monomethyl ethers of methyl chenodeoxycholate. The extent of formation of these artifacts with time has been studied. No detectable artifacts were found with 2,2-dimethoxypropane as the methylating agent.
