Potassium Carbonate → HCID 10409943, compound

Participants

Reaction Steps

A mixture of 6-bromomethyl-1-methyl-1,2-dihydroquinolin-2-one (0.1 g), 4-ethoxycarbonyl-4-(3-hydroxyphenyl)tetrahydropyran (0.098 g), potassium carbonate (0.057 g) and DMF (2 ml) was stirred at ambient temperature for 16 hours. The mixture was partitioned between diethyl ether and 0.5N aqueous hydrochloric acid. The organic layer was washed with water and brine, dried (MgSO4) and evaporated. The residue was purified by column chromatography using initially methylene chloride and then increasingly polar mixtures of methylene chloride and acetone as eluent. There was thus obtained an oil which was triturated in pentane to give 4-ethoxycarbonyl-4-[3-(1-methyl-2-oxo-1,2-dihydroquinolin-6-ylmethoxy)phenyl]tetrahydropyran (0.099 g, 60%), m.p. 109°-110° C.
