Procedure

Treatment of (±)-[7-(2,6-dichlorophenyl)-2,3-dihydro-1-benzofuran-2-yl]methyl 4-methylbenzenesulfonate (0.75 g, 1.67 mmol) with sodium azide (0.43 g, 6.67 mmol) generally according to the procedure described for Intermediate 98 afforded 0.48 g (90%) of (±)-[7-(2,6-dichlorophenyl)-2,3-dihydro-1-benzofuran-2-yl]methyl azide. Treatment of the azide with triphenylphosphine (0.393 g, 1.49 mmol) generally according to the procedure described for Example 21 afforded 0.348 g (71%) of (±)-1-[7-(2,6-dichlorophenyl)-2,3-dihydro-1-benzofuran-2-yl]methanamine as a white solid, hydrochloride salt. mp 206-208° C.; Anal. calcd. for C15H13Cl2NOHCl: C, 54.49; H, 4.27; N, 4.24. Found: C, 54.38; H, 4.36; N, 4.12.
