To a solution of (2S,4R)-1-tert-butyl 2-methyl 4-(6-aminopyridin-3-yl)pyrrolidine-1,2-dicarboxylate (250 mg, 0.778 mmol) in 2-methyl THF (18 mL) was added LiAlH4 (59 mg, 1.56 mmol). After 15 min, the reaction was quenched by the sequential addition of water (60 μL), 1 N NaOH aqueous solution (60 μL) and water (60 μL). The mixture was stirred vigorously for 5 min, and then filtered over Celite, rinsing with 2-methyl THF. The organics were concentrated to provide (2S,4R)-tert-butyl 4-(6-aminopyridin-3-yl)-2-(hydroxymethyl)pyrrolidine-1-carboxylate (230 mg, 100% yield). LCMS (m/z): 294.1 (MH+), 0.49 min.
