Procedure

Treatment of (±)-(5-chloro-2-methyl-7-{[(trifluoromethyl)sulfonyl]oxy}-2,3-dihydro-1-benzofuran-2-yl)methyl 4-methylbenzenesulfonate (5.00 g, 10.0 mmol) with phenylboronic acid (1.83 g, 15.0 mmol), dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloromethane adduct (0.82 g, 1.0 mmol), and potassium carbonate (2.76 g, 20.0 mmol) generally according to the procedure described for Intermediate 35 gave (±)-(5-chloro-2-methyl-7-phenyl-2,3-dihydro-1-benzofuran-2-yl)methyl 4-methylbenzenesulfonate. Treatment of (±)-(5-chloro-2-methyl-7-phenyl-2,3-dihydro-1-benzofuran-2-yl)methyl 4-methylbenzenesulfonate (4.1 g, 9.5 mmol) with sodium azide (3.9 g, 60.0 mmol) generally according to the procedure described for Intermediate 98 afforded (±)-2-(azidomethyl)-5-chloro-2-methyl-7-phenyl-2,3-dihydro-1-benzofuran. Treatment of the azide with sulfided platinum on carbon (0.350 g, 5 wt. %) generally according to the procedure described for Example 1 provided 2.0 g (64%) of (±)-1-(5-chloro-2-methyl-7-phenyl-2,3-dihydro-1-benzofuran-2-yl)methanamine as a white solid, hydrochloride salt. mp 222-225° C.; Anal. calcd. for C16H16ClNOHCl: C, 61.95; H, 5.52; N, 4.52. Found: C, 60.82; H, 5.67; N, 4.37.
