Reaction Steps

A mixture of 5.04 parts of 4-[5,5-dimethyl-2-(2-thienyl)-1,3-dioxan-2-yl]-2-nitrobenzenamine and 120 parts of methanol is hydrogenated at normal pressure and at room temperature with 3 parts of Raney-nickel catalyst. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated, yielding 4.5 parts (100%) of 4-[5,5-dimethyl-2-(2-thienyl)-1,3-dioxan-2-yl]-1,2-benzenediamine; mp. 178° C.
