실험 절차

To a stirred mixture of 0.100 g (0.257 mmol) of 4-(2,6-Dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-bicyclo[2.2.2]octane-1-carboxylic acid (Example 13), 0.039 g (0.257 mmol) of sarcosine hydrochloride, 0.143 ml (1.03 mmol) of NEt3, and 2 ml anhydrous acetonitrile was added 0.103 g (0.270 mmol) of HATU. The reaction solution was stirred at rt for 16 h. The reaction mixture was concentrated in vacuo and combined with 10 ml EtOAc and 10 ml of 10% citric acid. The aqueous layer was separated and washed twice with 10-ml portions of EtOAc. The combined organic fractions were washed with 10-ml portions of sat'd NaHCO3 and brine and conc'd in vacuo. The resultant solid was dissolved in a mixture of 5 ml of MeOH and 5 ml of 1 N NaOH and stirred for 16 h. The reaction solution was conc'd in vacuo, taken up in 10 ml of water, and washed twice with 10-ml portions of CH2Cl2. The aqueous layer was acidified with conc'd HCl and the resultant precipitate collected by suction filtration to give 0.094 g (77% yield) of an off-white solid. (MH+=460.18)
