Reaction Steps
To a solution of 0.5 M LiCN in DMF (30 mL) was added (R)-3-indol-2-yl-2-hydroxypropanyl p-toluenesulfonate (R)-2 (5.6 g, 16.2 mmol) and sodium cyanide (1.5 g, 30.6 mmol). The reaction mixture was stirred for 1 hour at 100° C., cooled to room temperature, poured into 80 mL ice-water, and extracted with ethyl acetate (3×50 mL). The combined organic solution was washed with saturated sodium bicarbonate (2×50 mL), brine (2×30 mL), dried over anhydrous sodium sulfate, and evaporated to yield a deep red oil. The oil was purified by flash chromatography (hexane:ethyl acetate 2:3) to give 2.4 g (74%) of the title compound as a light yellow solid.
