반응 단계
A mixture of 5-bromonicotinamide (0.201 g; 1.00 mmol), 4-formylphenyl boronic acid (0.180 g; 1.2 mmol), Pd(OAc)2 (0.0022 g; 0.010 mmol), S-Phos (0.0082 g; 0.020 mmol) and K2CO3 (0.345 g; 2.5 mmol) in n-butanol (3 mL) was sparged with nitrogen ca. 10 min, then heated at 80° C. for 1 h. Upon cooling, the mixture was poured into water, layered with Et2O and sonicated at room temperature ca. 5 min. Solid was collected by filtration, and the cake was air-dried on the filter, affording the title compound as a colorless solid which was used without further purification. LC/MS (method A) 1.57 min; m/z 227 (M+H).
