Reaction Steps
To a solution of 4-[(4-bromo-phenyl)-(6-methyl-pyridin-2-yloxy)-methyl]-piperidine-1-carboxylic acid tert-butyl ester (2.00 g, 4.33 mmol) and zinc cyanide (305 mg, 2.60 mmol) in DMF (20 mL) under nitrogen was added DPPF (48 mg, 0.087 mmol) and Pd2(dba)3 (40 mg, 0.043 mmol). The resulting suspension was warmed to 130° C. and stirred for 5 hours. Standard work-up and purification gave 4-[(4-cyano-phenyl)-(6-methyl-pyridin-2-yloxy)-methyl]-piperidine-1-carboxylic acid tert-butyl ester (1.4 g, 79%) as a yellow solid.
