Reaction Steps
Treatment of (±)-[7-chloro-4-(trifluoromethyl)-2,3-dihydro-1-benzofuran-2-yl]methyl 4-methylbenzenesulfonate (1.0 g, 2.46 mmol) with sodium azide (0.64 g, 9.83 mmol) generally according to the procedure described for Intermediate 98 provided (±)-2-(azidomethyl)-7-chloro-4-(trifluoromethyl)-2,3-dihydro-1-benzofuran. Treatment of the azide with palladium on carbon (0.060 g, 10 wt. %) generally according to the procedure described for Example 1 afforded 0.350 g (64%) of (±)-1-[7-chloro-4-(trifluoromethyl)-2,3-dihydro-1-benzofuran-2-yl]methanamine as a white solid, hydrochloride salt. mp >250° C.; Anal. calcd. for C10H9F3ClNOHCl: C, 41.69; H, 3.5; N, 4.86. Found: C, 41.78; H, 3.43; N, 4.77.
