Procedure

Following the procedure described by Ringold (H. J. Ringold, et al., J. Am. Chem. Soc. 78, 816, 1956), dehydroepiandrosterone (2.88 g, 10 mmol) dissolved in 85% formic acid (100 mL) is heated at 60° C. for 1 h. After cooling, the mixture is poured into iced water and after 16 h, crystals are filtered and dried in vacuo.
