    • Compound 1a was prepared by first dissolving LiTCNQ (2.570 mmol) in 20 mL of MeCN, followed by addition of a solution of N-octyl-4-methylpyridinium bromide (1.283 mmol) in 5 mL of MeCN. At reflux DBU (2.570 mmol) was added in increments of three drops every 15 min. After 14 h the reaction was stopped and the precipitate was filtered, washed with MeCN and dried under vacuum. The crude product was purified by washing with boiling methanol (70 mL) in a beaker, followed by filtering the undissolved portion. The process was repeated four times before the undissolved product was pure as analyzed by UV-vis.
