Procedure

A mixture of [7-(methylsulfonyl)-2,3-dihydro-1,4-benzodioxin-2-yl]methyl 4-methylbenzenesulfonate (0.7 g, 1.8 mmol), ethanamine (1 ml, 70% in water) and ACN (3 ml) was heated under microwave radiation at 120° C. for 30 min. Purification on flash column chromatography and on SCX-3 column (TEA/MeOH). Yield: 0.4 g, 72%. The amine was converted to the hydrochloric acid salt and was crystallized from MeOH/Et2O. M.p. 261° C. MS m/z (rel. intensity, 70 eV) 271 (M+, 19), 226 (4), 207 (9), 79 (6), 58 (bp).
