    • Synthesis of 2: a solution of 1 (0.232 g, 0.60 mmol, 4-pyridinecarboxylic acid chloride (0.255 g, 1.80 mmol, and Et3N (0.40 mL. 2.90 mmol) in CH2Cl2 (10 mL) was stirred at room temperature for 3 h. After the resulting Et2NHCl precipitate was filtered, the filtrate was concentrated to ca. 1 mL under vacuum and then subjected to TLC separation using petroleum ether/acetone (5/2 v/v) as eluent. 2 (0.247 g, 84, was obtained as a red solid from the major band.
