Procedure

Treatment of (±)-[5-chloro-7-(3-chlorophenyl)-2,3-dihydro-1-benzofuran-2-yl]methyl 4-methylbenzenesulfonate (1.00 g, 2.24 mmol) with sodium azide (0.93 g, 14.3 mmol) generally according to the procedure described for Intermediate 98 provided 0.41 g of (±)-2-(azidomethyl)-5-chloro-7-(3-chlorophenyl)-2,3-dihydro-1-benzofuran. Treatment of the azide with sulfided platinum on carbon (100 mg, 5 wt. %) generally according to the procedure described for Example 1 provided 0.31 g (50%) of (±)-1-[5-chloro-7-(3-chlorophenyl)-2,3-dihydro-1-benzofuran-2-yl]methanamine as a white solid, hydrochloride salt. mp 195° C. (dec); Anal. calcd for C15H13Cl2NOHCl: C, 54.49; H, 4.27; N, 4.24. Found: C, 51.59; H, 4.21; N, 4.02.
