الإجراء التجريبي

Preparation according to Example 1 but performed in one portion: 1-(2-bromoethoxy)-3-fluoro-5-methylsulfonyl-benzene (0.5 g, 1.68 mmol) and isopropylamine (1.15 ml, 13.46 mmol) in ethanol (4 ml). Purification by flash column chromatography (ethyl acetate/methanol, 100:0 to 85:15) gave the title compound (421 mg, 90.9%). The amine was converted to the hydrochloric acid salt and re-crystallized from methanol/diethyl ether: M.p. 173° C. MS m/z (relative intensity, 70 eV) 275 (M+, 4), 261 (16), 260 (41), 73 (32), 72 (bp).
