Reaction Conditions

Reaction Steps

A mixture of 5-bromo-6-methoxy-2-methylthioquinoline (6.1 g, 21 mmol) and CuCN (3.7 g, 41 mmol) in DMF (80 mL) was heated at 150° C. for 14 hours. The mixture was cooled and treated sequentially with 2:1 H2O/ethylenediamine (15 mL). The mixture was extracted with 1:1 EtOAc/hexane. The organic layer was worked-up. HPLC (1:8 EtOAc/hexane) gave 4.2 g (87%) of 5-cyano-6-methoxy-2-methylthioquinoline as a light yellow solid, (M+) 230(100).
