Vorschrift

To an ice cooled solution, under argon, of 7.3 g of p-nitrophenol and 7.5 ml of triethylamine in 36 ml of dry tetrahydrofuran, is added, dropwise, a solution of 10.78 g of p-nitrobenzyl chloroformate in 18 ml of dry tetraydrofuran. The reaction mixture, a suspension, is stirred at room temperature overnight. The formed solid is collected, washed with water and dried to give 5.9 g of the desired product.
