A mixture of 13.6 g (62 mmol) of 2-methyl-5-(4-nitro-phenyl)-pentan-3-one (Y. Huang, L. Shi, S. Li, Synthesis, 1988, 975-977), 400 mL of THF, and 2.6 g of Raney Nickel was shaken in a hydrogen atmosphere (24 p.s.i.) at 25° C. for 56 hours. The catalyst was filtered, and the filtrate was concentrated to give the title compound. 1H NMR (CDCl3) δ 1.01 (d, 6 H), 2.46-2.55 (m, 1 H), 2.65-2.83 (m, 4 H), 3.55 (br s , 2 H), 6.56 (d, 2 H), 6.92 (d, 2 H).
