Procedure

Treatment of (±)-(4-fluoro-7-phenyl-2,3-dihydro-1-benzofuran-2-yl)methyl 4-methylbenzenesulfonate (2.03 g, 5.09 mmol) with sodium azide (1.32 g, 20.38 mmol) generally according to the procedure described for Intermediate 98 provided (±)-2-(azidomethyl)-4-fluoro-7-phenyl-2,3-dihydro-1-benzofuran. Treatment of the azide with palladium on carbon (0.137 g, 10 wt. %) generally according to the procedure described for Example 1 gave 0.610 g (43%) of (±)-1-(4-fluoro-7-phenyl-2,3-dihydro-1-benzofuran-2-yl)methanamine as a white solid, hydrochloride salt. mp 254-257° C.; Anal. calcd. for C15H14FNOHCl: C, 64.4; H, 5.40; N, 5.01. Found: C, 64.98; H, 5.48; N, 4.79.
