実験手順
To a solution of 1-[[1,4-dihydro-4-oxo-5-(phenylmethoxy)-1-(phenylmethyl)-2-pyridinyl]-methyl]-4-(triphenylmethyl)-2,3-piperazinedione (8.77 g, 13.23 mmol) in 65 ml of dichloromethane was added dropwise at room temperature 65 ml of formic acid. After stirring for three days, the volatiles were distilled off in vacuo and the residue triturated twice with ether to give 5.24 g of 1-[[1,4-dihydro-4-oxo-5-(phenylmethoxy)-1-(phenylmethyl)-2-pyridinyl]methyl]-2,3-piperazinedione, melting point 260°-265° C.
