Ethyl 2-methyl-2-pyrrolidin-1-ylpropanoate (0.6162 g, 3.3308 mmol) was taken up in dry THF (5 mL). A 1M solution of LAH in THF (3.7 mL, 3.6639 mmol) was added drop wise. The reaction was warmed to 50° C. and stirred for 18 h. Cooleed to 0° C. in an ice bath and methanol (5 mL) was added slowly. The reaction was diluted with water (50 mL) and extracted with Et2O (2×50 mL). The organics were concentrated by blowing a slow stream of N2 over the flask to give 0.3578 g (2.0682 mmol, 62%) of the product as a light brown oil. 1H NMR (CDCl3) δ 3.22 (s, 2H), 2.61 (bs, 4H), 1.79 (bs, 4H), 1.01 (s, 6H).
