Procedure

To a solution of lithiumaluminum hydride (0.7 g, 18 mmol) in dry tetrahydrofuran (30 ml) the above propionic acid (2.6 g, 9.3 mmol) in dry diethyl ether (30 ml) was added. The reaction mixture was stirred at reflux temperature for 1.5 hour. The reaction was cooled on a ice bath and quenched by addition of water (0.7 ml), and 20% sodium hydroxide (0.7 ml), successively. The resulting mixture was filtered and the filtercake was washed with diethyl ether (2×100 ml). The phases were separated and the organic phase was evaporated in vacuo affording 2.6 g (100%) of 3-(11,12-dihydro-dibenz[a,e]cycloocten-5-yl)-1-propanol as an oil.
