Reaction Conditions

Reaction Steps

3-(5-Ammoniopentanoyl)pyridinium chloride (188 mg, 0.75 mmol) was transferred to a reaction vessel and treated with isopropanol (12 mL). 5-Phenyl-2-furaldehyde (193 mg, 1.12 mmol) was added, the reaction vessel was sealed, and the reaction was heated to 85° C. with stirring for 6 hours. The reaction was then cooled to room temperature, and the precipitate was recovered by vacuum filtration, washed with isopropanol and ether then dried under vacuum giving 264 mg (91%) of an orange solid. LC-MS: RT=5.15 min, [M+H]+=315.1.
