Procedure

Treatment of (±)-{7-[4-(trifluoromethyl)phenyl]-2,3-dihydro-1-benzofuran-2-yl}methyl 4-methylbenzenesulfonate (3.3 g, 7.34 mmol) with sodium azide (1.91 g, 29.38 mmol) generally according to the procedure described for Intermediate 98 gave (±)-2-(azidomethyl)-7-[4-(trifluoromethyl)phenyl]-2,3-dihydro-1-benzofuran. Treatment of the azide with palladium on carbon (0.205 g, 10 wt. %) generally according to the procedure described for Example 1 provided 1.82 g (75%) of (±)-1-{7-[4-(trifluoromethyl)phenyl]-2,3-dihydro-1-benzofuran-2-yl methanamine as a white solid, hydrochloride salt. mp >250° C.; Anal. calcd. for C16H14F3NOHCl: C, 58.28; H, 4.59; N, 4.25. Found: C, 57.47; H, 4.82; N, 3.65.
