실험 절차

tert-Butyl[(3R)-1-(4-nitrophenyl)pyrrolidin-3-yl]carbamate (Method 40; 1.0 g, 3.26 mmol) in DCM (15 ml) was reacted with TFA (7.5 ml) at room temperature for 18 hours. Pouring into cold ether (200 ml) gave on filtration the title compound (0.97 g, 93%). NMR: 2.03-2.17 (m, 1H), 2.22-2.44 (m, 1H), 3.40-3.60 (m, 3H), 3.68-3.74 (m, 1H), 3.95-4.08 (m, 1H), 6.66 (d, 2H), 8.08 (d, 2H), 8.14 (s, 2H).
