Reaction Steps

A mixture of 1-boc-6-iodo-1,2,3,4-tetrahydroquinoline (2.0 g, Reference Example 12), 5,6-dihydro-pyran-2-one (1.1 g), tetrakis(triphenylphosphine)palladium(0) and triethylamine (2.2 g) in dimethylformamide (5 ml) was stirred at about 95° C. in a sealed vessel under an atmosphere of nitrogen overnight. The reaction mixture was partitioned between ethyl acetate and dilute hydrochloric acid, the layers separated, and the organic layer washed with sodium bicarbonate solution, then dried, and then evaporated. The residue was subjected to flash chromatography on silica eluting with a mixture of ethyl acetate and cyclohexane (2:3,v/v) to give the title compound as a brown oil, 1.2 g.
