Reaction Steps

Methyl 1-(methylsulfonyl)pyrrolidine-2-carboxylate (1.1 g, 4.6 mmol) in anhydrous tetrahydrofuran (10 mL) was added slowly to a stirring suspension of lithium aluminum hydride (0.259 g, 6.8 mmol) in anhydrous tetrahydrofuran (10 mL) kept at 0° C. with an external ice bath. After fifteen minutes, the ice bath was removed and the reaction was allowed to warm to ambient temperature and stirred for an additional hour. The mixture was cooled to 0° C., and water (1 mL) was added dropwise, followed by 15% aqueous sodium hydroxide (1 mL), and water (3 mL). The mixture was stirred for 15 mins at room temperature, followed by the addition of magnesium sulfate and additional stirring. The mixture was filtered through Celite, washed three times with ether, and the combined organic fractions concentrated under reduced pressure to afford a yellow oil (0.7 g, 77%). 1H NMR (CDCl3, 300 MHz) δ 3.78-3.57 (m, 3H), 3.49-3.36 (m, 2H), 2.87 (s, 3H), 2.64 (br s, 1H), 2.09-1.82 (m, 4H).
