Participants

Reaction Steps

1.4 g of sodium cyanoborohydride were added to a solution of 7 g of 4-hydroxy-1-N-(β-hydroxypropyl)indole, obtained in the preceding stage, in 40 cm3 of acetic acid, the temperature being maintained below 30° C. After stirring for 30 minutes, the reaction mixture was poured onto 200 g of ice-cold water and the pH was neutralized to 7.5 by addition of 30% aqueous ammonia. The precipitate obtained was filtered off and dried. 4 g of the expected product were obtained, the melting point of which was between 130° and 131° C. and the elemental analysis of which, calculated for C11H15NO2, was as follows:
