Water → 4-(4-Methylthiophenoxy)benzylamine

Participants

Reaction Steps

To a stirred mixture of potassium phthalimide (3.60 g, 19.4 mM) and dry N,N-dimethylformamide (200 ml) was added dropwise a solution of 4-(4-methylthiophenoxy)benzylbromide (5.00 g, 16.2 mM) in dry N,N-dimethylformamide at room temperature, the mixture was stirred for 5 h at the same temperature. The mixture was poured into water, and the mixture was extracted with toluene. The extract was washed with 5N NaOH, water and brine, dried with magnesium sulfate, and concentrated in vacuo. The residue was diluted with methanol (200 ml), and to the mixture was added dropwise hydrazine monohydrate (1.10 g, 21.1 mM). The mixture was stirred for 6 h under reflux, and this was cooled to the room temperature and concentrated in vacuo. The residue was diluted with chloroform and the mixture was filtered through celite. The filtrate was washed with 5N NaOH(x3) and brine(x2), dried with potassium carbonate, and concentrated in vacuo to give 4-(4-methylthiophenoxy)benzylamine (3.02 g, 76%) as colorless crystals, m.p. 61.8° C.
