PROCESSES FOR THE PREPARATION OF MODAFINIL AND ANALOGS THEREOF

摘要

The present invention generally relates to an improved process for preparing modafinil and analogs thereof. The process minimizes impurities and improves the overall yield by oxidizing a modafinil intermediate compound in a reaction mixture including an alcohol and an organic acid at a ratio of from about 1:1 to about 80:1 (by volume).
