Versuchsvorschrift

A mixture of 4-(5-bromopyridin-2-yl)thiomorpholine 219-2 (2.37 g, 9.15 mmol), diethyl malonate (2.04 g, 12.8 mmol), Pd(OAc)2 (102 mg, 0.46 mmol), biphenyl-2-yl-di-tert-butylphosphine (270 mg, 0.9 mmol) and t-BuONa (1.76 g, 18.3 mmol) in toluene (45 ml) was stirred under argon at 98° C. for 1 hour. After cooled to room temperature, the mixture was filtered through celite and washed with ethyl acetate. The filtrate was evaporated and the residue was subjected to silica gel column chromatography to give diethyl 2-(6-thiomorpholinopyridin-3-yl)malonate 219-3.
