反応手順

To a thin suspension of 4-carboxybenzaldehyde (600 g, 3.92 mol) in tetrahydrofuran (2664 g, 36.57 mol) was added dimethylformadehyde (11.48 g, 0.16 mol) and the reaction mixture was cooled to 0-5° C. with an ice bath. The reaction mixture was then stirred at 0° C. while oxalyl chloride (608.69 g, 4.70 mol) was added slowly. The reaction mixture was stirred until it was deemed complete by 1HNMR to yield the title compound. The reaction mixture was used in the next step without further manipulation.
