Reaction Steps

(800 mg, 2.42 mmol) 1-(5-Iodopyridin-2-yl)-3,3-dimethylpyrrolidine-2,5-dione (Example 13, step 1) was dissolved in THF (6 ml) and MeOH (2 ml) and the solution was cooled to 0-5° C. NaBH4 (101 mg, 2.67 mmol, 1.1 equiv.) was added at 0-5° C. and the mixture was stirred for 1 hr at 0-5° C. The reaction mixture was extracted with sat. NaHCO3 solution and two times with a small volume of dichloromethane. The crude product was purified by flash chromatography by directly loading the dichloromethane layers onto a amino-silica gel column and eluting with a ethyl acetate/heptane gradient, 0:100 to 100:0. The desired (5-RS)-5-hydroxy-1-(5-iodo-pyridin-2-yl)-4,4-dimethyl-pyrrolidin-2-one (370 mg, 46% yield) was obtained as a white solid, MS: m/e=333.0 (M+H+).
