Reaction Steps

A mixture of [(2R)-5-chloro-7-(methylsulfonyl)-2,3-dihydro-1,4-benzodioxin-2-yl]methyl 4-methylbenzenesulfonate (0.48 g, 1.1 mmol), methanamine (1.5 ml, 33% in EtOH, 4 mmol) and ACN (3 ml) was heated under microwave radiation at 120° C. for 20 min. Purification on SCX-3 column (TEA/MeOH) and by flash column chromatography (MeOH/EtOAc) gave the title compound (0.18 g). The amine was converted to the hydrochloric acid salt and crystallized from MeOH/Et2O. M.p. 262° C. MS m/z (rel. intensity, 70 eV) 291 (M+, 43), 113 (57), 85 (80), 70 (bp), 63 (84), 50 (60) [α]=−61° (MeOH).
