실험 절차

Intermediate IV (150 g, 0.44 mol) was added to glacial acetic acid (8v/w, 1200 mL). The mixture was warmed up to 40° C. After Intermediate IV was dissolved completely, iron powder (123.1 g, 2.20 mol) was slowly added in batch. The mixture was warmed up to 80° C. and reacted under mechanical stirring for 2 h. After completion of the reaction, the reaction solution was filtered by suction when it is still hot. The filtrate was collected. After cooling the filtrate, a great deal of solid separated out and was filtered by suction to produce a lutescens solid. The filtered cake was dissolved in glacial acetic acid. The mixture was stirred at 80° C. for about 30 min, and was filtered by suction again when it is still hot. The filtrate was collected. After cooling the filtrate, a solid separated out and was filtered by suction to produce a lutescens solid. The solids were combined, and washed with water several times until the filtrate became neutral. The filtered cake was dried to produce a pale yellow solid (79 g) in a yield of 65%.
