Reaction Steps

Compound (8) (0.00170 mol) was dissolved in HCl, 6N (20 ml), and immediately warmed in an oil bath at 100° C. under nitrogen for 200 minutes. The heat was turned off, and the sample was cooled to 0° C. 3 N NaOH (35 ml) was slowly added. Basification was completed with saturated NaHCO3. The sample was extracted with chloroform. The combined organic phases were dried, filtered, and the resulting solution was used without further purification in further synthesis, yielding (S)-2,3-dihydro-2-(4-propyl-1H-imidazol-2-yl)-1H-indole (intermediate 5).
