Procedure

4-Nitrophenylchloroformate (260 g, 1.30 mmol) as a solution in 500 ml dichloromethane (DCM) is added to Wang resin (p-benzyloxybenzyl alcohol resin ex Calbiochem-Nova-biochem, 350 g, 0.60 mmol) suspended in 1000 ml DCM and N-methylmorpholine (196 ml, 1.79 mmol) and stirred at room temperature for 18 hours. The resin is filtered and washed successively using methanol, DCM and ether to give WANG PARA-NITROPHENOL RESIN. [IR. 1761.5 cm−1; Loading 1.20 mmol/g].
