참여 물질

반응 단계

To a suspension of LiAlH4 (4.7 g) in diethyl ether (200 ml) was added dropwise a solution of AlCl3 in diethyl ether (200 ml). A solution of 1-indanecarboxylic acid (10 g) (prepared according to the method of Hansen et al. Helv. Chim. Acta 1982, 33, 325-343) in dry tetrahydrofuran (200 ml) was added drop-wise at 10-15° C. The mixture was finally stirred at room temperature for 1.5 hours. Excess AlH3 was destroyed by addition of concentrated aqueous NaOH solution (25 ml) at 0° C. Precipitated inorganic salts were filtered off and the solvents evaporated in vacuo leaving 6.8 g of the title compound 1a as a viscous oil which was used without further purification.
