Participants

Reaction Steps

5′-(5-Cyano-1-methyl-1H-pyrrol-2-yl)spiro[cyclohexane-1,3′-[3H]indol]-2′-ylidenecyanamide (16 g) in THF (100 mL) was treated with diethylamine (37 g) and refluxed until a solution was obtained. Upon cooling to ambient temperature, a white precipitate was formed. The solution was filtered, the precipitate washed with THF and dried to give 18.0 g (90% yield) of the diethylamine salt/complex. 1H NMR (DMSO-d6, ppm): 7.58, 7.21, 7.05, 7.00, 6.5-6 (br), 6.27, 3.71, 2.80 (q), 1.9-1.7, 1.5-1.4, and 1.10 (t).
