Reaction Steps

A 250-mL round-bottomed flask was charged with 2-iodopyridine (1.0 g, 4.88 mmol) and 50 mL of THF. The resulting mixture was cooled to −100° C. and then n-BuLi (2.5 M in hexanes, 5.3 mL, 13 mmol) was added at such a rate that the internal temp did not rise above −97° C. After 15 min at −100° C., (E)-N-(3,4-dichlorobenzylidene)-2-methylpropane-2-sulfinamide (1.36 g, 4.88 mmol) was added and stirring was continued for 1 h at −100° C. 30 mL of 1M HCl in ether was added, and the mixture was allowed to warm to rt. Once at rt, 5 mL of MeOH was added and the mixture was stirred for an additional 1 h. The resulting precipitate was collected by filtration to give (3,4-dichlorophenyl)(pyridin-2-yl)-methanamine hydrochloride as a white solid.
