Procedure

A mixture of 2.8 g of 5-hydroxy-pyrrolidin-2-one in 25 cm3 of ethylmercaptan is made to react for 4 hours at 20° C. with 1.4 g of Amberlite IR 120 H. The mixture is diluted with ethyl ether, the solvent is distilled off, and 2.6 g of the expected product is obtained, m.p. 65°-68° C. after crystallizing from isopropyl ether, m.p. 68°-70° C.
