Reaction Steps

A solution of 4.0 g (21 mmol) of methyl 3-methyl-4-nitrohexanoate (from step A) in 20 mL of EtOH containing 0.4 g of PtO2 was hydrogenated on a Parr apparatus for 3 days. The catalyst was filtered and washed with EtOH and the filtrate was concentrated. Vacuum distillation of the residue furnished 1.6 g (61%) of the title compound: bp 102°-107° C./2 mm.
