Reaction Steps

Into a solution of 5.01 g (40 mmol) of 1-methyl-3-pyrrolecarboxylic acid and 16.87 g (48 mmol) of β-alanine benzyl ester p-toluenesulfonate in 200 ml of dimethylformamide (hereinafter called “DMF”), a solution of 7.83 g (48 mmol) of diethyl phosphorocyanidate in 50 ml of DMF was added dropwise under ice cooling and stirring. A solution of 9.71 g (96 mmol) of triethylamine in 50 ml of DMF was then added dropwise, and the reaction mixture was stirred at room temperature for 67 hours.
