Procedure

Compound 6 (8 g, 33.7 mmol) was dissolved in dry DMF (80 ml) under a nitrogen atmosphere. The solution was cooled at 0° C. and NaH (1.62 g, 37.13 mmol, 60% dispersion) was carefully added portionwise. When the nitrogen evolution ceased, bromoacetamide (5.6 g, 37.13 mmol) was added. After 30 minutes, the mixture was poured into cold water and the solid filtered off, washed with water and hexane. The crude material was directly cristallized in acetonitrile affording 2-[(5′-methyl-2′-oxospiro[1,3-dithiolane-2,3′-indol]-1′(2′H)-yl]acetamide 15 as a white solid.
