2-Amino-5-bromopyridine → HCID 88658071, compound

Participants

Reaction Steps

A solution of 1-(3-chlorophenylsulphonyl)-2-ethoxy-1-phenylsulphonylethene (3.13 g) and 2-amino-5-bromopyridine (1.4 g) in dimethylacetamide (20 ml) was heated at reflux for 3.5 hours. The solution was cooled and poured onto ice (200 g), and the resulting pale yellow solid was filtered off and recrystallised from aqueous ehtaol (95% v/v), to give 2-(5-bromopyrid-2-ylamino)-1-(3-chloropheylsulphonyl)-1-phenylsulphonylethene (2.5 g), m.p. 170°-172° C.
