Reaction Steps

Serotonin hydrochloride hemihydrate (222 mg), N-(4-methoxyphenyl)-7-oxo-octanamide (263.3 mg), and methanol (10 mL) were stirred in the dark and the resulting solution treated with sodium cyanoborohydride (95 mg). After 4 d at ca. 22° C., sodium bicarbonate (350 mg) and water (10 mL) were added. After stirring 1.5 hours, the mixture was extracted with 1:4 2-propanol:dichloromethane (3×25 mL) and the combined extracts were dried (Na2SO4) and concentrated in vacuo. Chromatography eluting with 4:10:90, then 3:30:70 triethylamine:ethanol:ethyl acetate gave a component with an Rf of 0.3 in the latter solvent system. This oil was reconcentrated twice from ethanol (50 mL), then redissolved in ethanol (ca. 50 mL), treated with 1:9 concentrated hydrochloric acid:ethanol (1.2 mL), and reconcentrated in vacuo to a pale yellow oil which foamed to a solid. This was the title compound (352 mg), isolated as a pale yellow solid.
