Mode opératoire

Preparation according to Example 1 but performed in one portion: 1-(2-bromoethoxy)-3-chloro-5-methylsulfonyl-benzene (0.5 g, 1.59 mmol) and propane-1-amine (1.04 ml, 12.76 mmol) in ethanol (5 ml). Yield: 368 mg (79.1%). The amine was converted to the hydrochloric acid salt and re-crystallized from ethanol/diethyl ether: M.p. 195-197° C.
