Procedure

A solution of 4-chloro-2-nitro-1-(phenylthio)benzene (11.0 g) and Raney nickel in ethanol (3A; 9.3 mL) was reacted in a Parr Hydrogenator under hydrogen atmosphere at 5 psi and room temperature. When the theoretical amount of hydrogen uptake was reached, the reaction was filtered to remove the catalyst and evaporated in vacuo to yield 8.61 g (88%) of a light orange solid. mp: 59°-61° C.
