Participants

Reaction Steps

To a 0° C. solution of 4-(1-methyl-piperidin-4-yl)-butan-1-ol (0.74 g, 4.37 mmol), 3-hydroxy-benzonitrile (0.52 g, 4.37 mmol), and 3 mmol/g polymer supported PPh3 (2.30 g, 8.73 mmol) in THF (40 mL) was added diisopropyl azodicarboxylate (1.72 mL, 8.73 mmol) dropwise. After 6 h the mixture was filtered and concentrated. Purification by Method 1 afforded 840 mg (71%) of a yellow oil. MS (ESI): mass calcd for C17H24N2O, 272.19; m/z found, 273.4 [M+H]+. 1H NMR (400 MHz, CDCl3): 7.38-7.33 (m, 1H), 7.24-7.20 (m, 1H), 7.14-7.09 (m, 2H), 3.96 (t, J=6.4, 2H), 2.88-2.80 (m, 2H), 2.26 (s, 3H), 1.94-1.84 (m, 2H), 1.82-1.73 (m, 2H), 1.72-1.64 (m, 2H), 1.52-1.42 (m, 2H), 1.34-1.17 (m, 5H).
