Reaction Steps

Di-tert.-butyl 2-[4(S)-(2-tetrahydropyranyloxy)nonyl]-2-(6-ethoxycarbonylhexyl)malonate (47.8 g., 0.08 mole) is added to a mixture of tetrahydrofuran (300 ml.) and 6N hydrochloric acid (15 ml.). The resulting solution is allowed to stand at room temperature for 6 hours. The solution is then diluted with 1.5 liters of water. The oily product is taken up in ether, washed with four portions of water, and with brine and dried over sodium sulfate. Distillation of the ether in vacuo leaves the title compound as a residual oil weighing 39.5 g.
