YieldReaction ConditionsOperation in experiment
50% With ammonium chloride In ethanol at 0 - 20℃; A mixture of terephthalaldehyde (10 g, 74.55 mmol), ammonium chloride (160 mg, 3.0 mmol) in ethanol (10.3 g, 223.6 mmol) was added dropwise triethoxymethane (12.15 g, 82 mmol) at 0° C. After the addition, the mixture was stirred at room temperature overnight. The mixture was concentrated, the residue was purified by silica gel chromatography to give the title compound (7.0 g, yield 50percent) as a white solid. LC-MS (ESI) m/z: 209 (M+1)+
