Synthesis of 2-[N-(a-picolyl)amino]-benzophenone (1)
Thionyl chloride (3.5 mL, 50 mmol) was added dropwise
to a stirred solution of picolinic acid (6.2 g, 50 mmol)
and Et3N (10.4 mL, 75 mmol) in CH2Cl2(35 mL) at 0C.
The mixture was stirred for 20 min, and then a solution

another 2 h at room temperature, and the reaction mixture
