piperidine prepared by adding sodium acetate (1.50 g) to 1 M acetic acid (100 mL). The substrate (50 mg, 0.23 mmol) was then added followed by methanol (10 drops) to give a homogeneous mixture. After 3 hat room temperature, 15% sodium hydroxide (1 mL) was added followed by extraction with CHjCb (2X3 mL) after which the extracts were dried and concentrated. The products were isolated as oils.trans-l-Methyl-2-phenyl-4-(2-methylaminoethyl)pyrrolidine (8a): bp 58-60 °C (0.005 mm) (bulb to bulb); NMR 6 7.2 (s, 5 H), 3.3 (d of d, 1 ), 3.1 (t, 1 H), 2.4 (s, 3 H), 2.2 (s, 3 ), 1.4-2.8 (m, 8 ), 1.1
