Reaction Steps
[1-(3-Methyl-1,2,4-oxadiazol-5-yl)-4-piperidinyl]methanol (143 mg, 13%) was prepared from a solution of 1N ZnCl2 in Et2O (6.8 mL, 6.8 mmol), 4-(hydroxymethyl)-1-piperidinecarbonitrile (prepared as in Example 20, Step 1, 0.79 g, 5.6 mmol) and N-hydroxyacetamidine (0.5 g, 6.8 mmol) in EtOAc (10 mL) followed by concentrated HCl (2 mL) in EtOH (2 mL) in a manner similar to Example 20, Step 3. 1H NMR (400 MHz, CDCl3): δ 4.22-4.10 (m, 2H), 3.54 (d, 2H, J=6.4 Hz), 3.11-3.01 (m, 2 H), 2.21 (s, 3H), 1.89-1.79 (m, 2H), 1.78-1.69 (m, 1H), 1.41-1.20 (m, 2H); LRMS (ESI), m/z 198 (M+H).
