Reaction Steps
Treatment of (±)-(5-methyl-3,6,7,8-tetrahydro-2H-indeno[4,5-b]furan-2-yl)methyl 4-methylbenzenesulfonate (0.862 g, 2.40 mmol) with sodium azide (0.469 g, 7.21 mmol) generally according to the procedure described for Intermediate 24 gave (±)-(5-methyl-3,6,7,8-tetrahydro-2H-indeno[4,5-b]furan-2-yl)methyl azide. Treatment of the azide with palladium on carbon (10 wt. %, 0.055 g) generally according to the procedure described for Example 2 gave 0.460 g (80%) of (±)-1-(5-methyl-3,6,7,8-tetrahydro-2H-indeno[4,5-b]furan-2-yl)methanamine as a white solid, hydrochloride salt. mp>200° C. (dec.); Anal. calcd. for C13H17NOHCl: C, 65.13; H, 7.57; N, 5.84. Found: C, 64.97; H, 7.61; N, 5.67.
