Reaction Steps

Treatment of (±)-[7-(2,4-difluorophenyl)-2,3-dihydro-1-benzofuran-2-yl]methyl 4-methylbenzenesulfonate (4.3 g, 10.37 mmol) with sodium azide (3.03 g, 46.68 mmol) generally according to the procedure described for Intermediate 98 gave 2.91 g (98%) of (±)-[7-(2,4-difluorophenyl)-2,3-dihydro-1-benzofuran-2-yl]methyl azide. Treatment of the azide with palladium on carbon (0.29 g, 10 wt. %) generally according to the procedure described for Example 1 afforded 2.3 g (76%) of (±)-1-[7-(2,4-difluorophenyl)-2,3-dihydro-1-benzofuran-2-yl]methanamine as a white solid, hydrochloride salt. mp 222-224° C.; Anal calcd. for C15H13F2NOHCl: C, 60.51; H, 4.74; N, 4.7. Found C, 60.65; H, 4.76; N, 4.51.
