Versuchsvorschrift

To a solution of (9-benzyl-1,8-diethyl-1,3,4,9-tetrahydro-pyrano[3,4-b]indol-1-yl)-acetic acid (0.45 g, 1.2 mmol) in tetrahydrofuran at room temperature was added 1.0 M solution of borane-tetrahydrofuran complex in tetrahydrofuran and it was stirred at 90° C. for 4 hours. The mixture was quenched with 5% HCl solution and stirred at room temperature for 20 minutes. It was extracted with ethyl acetate and washed with saturated sodium bicarbonate. The extracts were dried over magnesium sulfate and evaporated to dryness. Flash chromatography on silica gel provided 0.321 g (74%) of the title compound as a solid. 1H NMR (500 MHz, CDCl3) δ 7.17 (m, 3H), 6.94 (d, 1H), 6.84 (m, 2H), 6.70 (t, 1H), 6.56 (d, 1H), 3.87 (m, 1H), 3.79 (m, 1H), 3.68 (dt, 1H), 3.64 (br, 1H), 3.41 (td, 1H), 2.93 (q, 2H), 2.43 (q, 2H), 2.04 (m, 1H), 1.93 (dt, 1H), 1.86 (m, 1H), 1.77 (m, 1H), 1.49 (m, 1H), 1.38 (m, 1H), 1.17 (t, 3H), 0.70 (t, 3H).
