Procedure

Treatment of (±)-(6-methoxy-2,3-dihydro-1-benzofuran-2-yl)methyl 4-methylbenzenesulfonate (1.00 g, 2.99 mmol) with sodium azide (0.78 g, 11.96 mmol) generally according to the procedure described for Intermediate 98 afforded (±)-2-(azidomethyl)-6-methoxy-2,3-dihydro-1-benzofuran. Treatment of the azide with palladium on carbon (0.06 g, 10 wt. %) generally according to the procedure described for Example 1 gave 0.442 g (69%) of (±)-1-(6-methoxy-2,3-dihydro-1-benzofuran-2-yl)methanamine as a white solid, hydrochloride salt. mp >220° C.; Anal. calcd. for C10H13NO2HCl: C, 55.69; H, 6.54; N, 6.49. Found: C, 55.29; H, 6.48; N, 6.38.
