Participants

Reaction Steps

3.50 g of 2-(4-chloro-2-nitrophenoxy)-4-methoxy-benzaldehyde, prepared as described above in Example 5, in tetrahydrofuran (THF) (35 mL) was shaken in a Parr hydrogenator at 5 psi hydrogen with Raney nickel at 25° C. for 6 hours. The catalyst was filtered from the reaction and the solution evaporated in vacuo. The crude product was chromatographed, as described above in Example 2, through silica gel 60 using hexane:ethyl acetate (2:1), and recrystallized from ethanol (3A) to yield 1.79 g (60.1%) of product as white crystals.
