PROCEDURE
实验过程
A mixture of [5-fluoro-7-(methylsulfonyl)-2,3-dihydro-1,4-benzodioxin-2-yl]methyl 4-methylbenzenesulfonate (0.3 g, 0.8 mmol), ethanamine (1 ml, 70% in water) and ACN (2 ml) was heated under microwave radiation at 120° C. for 20 min. Purification on SCX-3 column (TEA/MeOH) and on flash column chromatography (Isooctane/EtOAc/MeOH). Yield: 0.1 g, 61%. The amine was converted to the hydrochloric acid salt and crystallized from EtOH. M.p. 256° C. MS m/z (rel. intensity, 70 eV) 289 (M+, 12), 70 (17), 59 (20), 58 (bp), 56 (19).
