Reaction Steps

Dimethyl acetylsuccinate (10 g, 53 mmol) was added to methanol (200 ml) followed by ammonium formate (34 g, 530 mmol) and NaBH3CN (3.4 g, 53 mmol) at 25° C. After 24 h the methanol was removed in vacuo to leave a white mass. Methylene chloride was added and the mixture filtered. The methylene chloride was evaporated resulting in an oil which was dissolved in 1N HCl (200 ml) and extracted with ether (100 ml). The ether layer was discarded and the aqueous layer was made basic using solid K2CO3. The product was extracted into methylene chloride, dried over Na2SO4, and evaporated to give dimethyl-2-(aminoethyl)succinate (6 g) . 1H NMR (d6-DMSO) δ 0.97 (d, 3H, J=7.1 Hz), 2.66 (m, 2H), 3.05 (m, 1H), 3.56 (s, 3H), 3.60 (s, 3H), 4.15 (m, 1H); MS (FAB) m/z 190.2 (MH+), 158.2, 141.2.
