Reaction Conditions

Reaction Steps

A solution of (239 g, 1.2 mol) 4-tert-butyl-1-methyl-2-nitro-benzene (M. S. Carpenter, W. M. Easter, T. F. Wood, J. Org. Chem. (1951), 586) in MeOH (1.0 L) was treated with Raney nickel (25 g) in a Parr shaker. The apparatus was sealed under hydrogen pressure to 52 psi, heated to 35° C. for 15 hours, and cooled to room temperature. The apparatus was vented and the contents filtered. The filtrate was concentrated in vacuo and distilled, collecting the major fraction (75-85° C., 1.0 torr). 1H NMR (CDCl3) δ 1.26 (s, 9 H), 2.11 (s, 3 H), 3.54 (bs, 2 H), 6.69 (d, 1 H), 6.72 (dd, 1 H), 6.96 (d, 1 H).
