2-[2-(1H-indol-3-yl)ethylamino]ethanol

Conditions: temp:-10.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 398 g of the product of Step A were dissolved in 4 liters of tetrahydrofuran cooled to +10° C. and while maintaining this temperature, 400 g of 25% sodium diethyl dihydroaluminate in toluene were introduced. The mixture was stirred for 90 minutes while allowing the temperture to rise to 17° C. The medium was cooled to -10° C. and 400 ml of sodium hydroxide solution in 1200 ml of water were introduced over 80 minutes while keeping the temperature at 0° C. during the introduction. The mixture was stirred for 2 hours at +10° C. then allowed to rise to ambient temperature for 16 hours with slower stirring. After decanting, the organic phase was washed with water and the wash water was extracted with ethyl acetate and methylene chloride. The combined organic phases were diluted with methylene chloride and dried, and the solvents were expelled at 40° C. under reduced pressure. The residue was triturated in 1300 ml of ethyl acetate for one hour, separated, washed with ethyl acetate and dried to obtain 240.8 g of the expected product melting at 92° C. cooled to +10° C. were introduced to rise to 17° C at 0° C. The mixture was stirred for 2 hours at +10° C. to rise to ambient temperature for 16 hours with slower stirring After decanting the organic phase was washed with water the wash water was extracted with ethyl acetate and methylene chloride The combined organic phases were diluted with methylene chloride dried were expelled at 40° C. under reduced pressure The residue was triturated in 1300 ml of ethyl acetate for one hour separated washed with ethyl acetate dried
