Participants

Reaction Steps

2-Thianaphthylmagnesium bromide is prepared from 2-thianaphthyllithium and MgBr2.OEt2. Using a procedure similar to that of Example 2, 3.85 g crude silylate product is isolated. Usual flash chromatography work-up results in an unidentified, insoluble purple solid. The desired product is isolated by adding 1M ethanolic HCl (95% of theoretical) to an ethereal solution of the free base. The product is a pale yellow solid (1.7 g, 72%); mp 235° C. (dec) (EtOH).
