実験手順

The combined mother liquors were evaporated and the salt was free-based in dichloromethane as described above for 106b prior to adding L-tartaric acid (400 mg, 2.66 mmol) in 20 mL of methanol. The exact recrystallization procedure was repeated as described above; obtained 168 mg of 5-((1R,5R)-3-azabicyclo[3.1.0]hexan-1-yl)-3-methyl-1,2,4-oxadiazole (106a). The optical purity (99.5%) was determined by HPLC analysis (Chiral Technologies Chiral-AGP, 4.0 mm×150 mm, 0.5% methanol, 20 mM sodium phosphate pH=7). (106a) MS (ESI) m/z 165.8 [M+H]+. 1H NMR (DMSO-d6) δ: 1.44 (m, 2H), 2.23 (m, 1H), 2.28 (s, 3H), 3.06 (s, 2H), 3.35 (m, 2.H), 4.13 (s, 2H).
