Reaction Steps

Preparation according to Example 2 using [(2R)-7-(trifluoromethylsulfonyl)-2,3-dihydro-1,4-benzodioxin-2-yl]methyl-4-methylbenzenesulfonate (0.27 g, 0.68 mmol), ethanamine (1 ml, 70% in water) and ACN (2 ml). Yield: 0.170 g, 76%. The amine was converted to the hydrochloric acid salt and recrystallized from acetonitrile. M.p. 208° C. MS m/z (rel. intensity, 70 eV) 325 (M+, 1) 58 (bp), 56 (8), 79 (5), 59 (4). [α]=−40° (MeOH).
