Reaction Steps
A solution of ethyl 1-isopropylpiperidine-4-carboxylate (10.0 g, 50.2 mmol) in THF (250 mL) at 0° C. was treated with lithium aluminum hydride (2.1 g, 55 mmol). After 1 h, the mixture was treated with a saturated aqueous solution of sodium potassium tartrate, partitioned with EtOAc, and the aqueous layer washed with EtOAc (2×). The combined extracts were dried (Na2SO4), concentrated, and the residue purified by column chromatography (SiO2: 10% methanol:methylene chloride) affording 4.30 g (54%) of the title compound.
