    • Since this reaction requires high concentration of reactants, uniform heating at such high temperature in large scale synthesis is difficult, resulting in poor yields of DNTT. Instead of enlargement of synthetic scale, several parallel reactions at relatively small scale (∼4 mmol) easily afforded more than 1 g of DNTT after purification
