실험 절차
A 250 mL round bottom flask was charged with 2-(4-nitrophenyl)ethanimidamide hydrochloride (approximately 6.47 g, 30.0 mmol, 48% purity), triethyl ethane-1,1,2-tricarboxylate (7.60 mL, 33.0 mmol) and methanol (43 mL). To this solution was added a 25% sodium methoxide solution in methanol (24.0 mL, 105.2 mmol) immediately resulting in a dark purple thick suspension. After stirring for three hours under reflux the dark purple mixture was cooled to 0° C. using an ice bath and carefully treated with 30 mL water. This mixture was slowly treated with 35 mL 6N hydrochloric acid giving a pale green suspension. The suspension was stirred for additional 30 minutes, filtered and the obtained fawn solid was washed with 100 mL water. The product was dried in a desiccator under vacuum for two days. The crude product was used without purification in the next step.
