Conditions

Temperature: 70 °C

Procedure

A mixture of 8-hydroxy-2-methylimidazo[1,2-a]pyridine (296 mg), 1,3-dichloro-2-(2-mesyloxyethyl)benzene (645 mg) and potassium carbonate (828 mg) in N,N-dimethylformamide (12 ml) was stirred for 6 hours at 70° C. The mixture was treated according to a similar manner to that of Preparation 16 to give 8-[2-(2,6-dichlorophenyl)ethyloxy]-2-methylimidazo[1,2-a]pyridine (150 mg).
