実験手順

To a solution of 8-chloro-3-pentyl-7-(2-propen-1-yl)-3,7-dihydro-1H-purine-2,6-dione (0.086 g, 0.29 mmol) and 3-(4-bromobutyl)-1-(phenylmethyl)-2-pyrrolidinone (0.17 g, 0.55 mmol, 1:1 mixture with 2-(phenylmethyl)-2-azaspiro[4.4]nonan-1-one) in THF (5 ml) was added potassium carbonate (0.08 g, 0.58 mmol) and the mixture heated and stirred at 50° C. for 18 h. The solution was allowed to cool then degassed (sequential evacuation followed by addition of nitrogen×3) and Pd(PPh3)4 (0.09 g, 0.077 mmol) followed by morpholine (0.2 ml, 2.2 mmol) added and the solution stirred at ambient temperature for 18 h. The solution was separated between ethyl acetate and dil HCl and the organics washed with brine, dried and concentrated. Purification of the residues using an aminopropyl SPE (5 g) eluting first with MeOH then 5% AcOH/MeOH yielded the title compound as a yellow oil which crystallised on standing under ether (0.031 g, 22%).
