Reaction Steps

2-dimethylaminoethanethiol hydrochloride (1.85 g, 13.09 mmol) was suspended in dry DMSO and sodium hydride (60% dispersed in mineral oil, 1.10 g, 2.1 equivs) was added carefully. The reaction mixture was left stirring for 1 hour before 5-bromo-2-thiophenecarboxaldehyde (2.5 g, 1.56 ml, 13.09 mmol) was added. The reaction mixture was then heated to 90° C. under nitrogen.
