An efficient process for the preparation of chirally pure obeticholic acid [1, (6α, 7α), OCA] with an overall yield of 30.78% from compound 5 (CDCA) is presented in this article. During the process development, there is a requirement for characterization of physical samples of all the possible diastereomers of 1 such as 2 (6β, 7α), 3 (6β, 7β), and 4 (6α, 7β) to designate the peaks for the quantitative
