Reaction Steps

To a solution of 8-(4-amino-benzyl)-1-benzyl-3-butyl-3,7-dihydro-purine-2,6-dione (60 mg) in N,N-dimethylformamide (2 mL) was added 6,6-dimethyl-5,7-dioxa-spiro[2.5]octane-4,8-dione (Lancaster) (34 mg) and the mixture heated to 100° C. under argon for 16 hrs. The reaction mixture was cooled to RT and poured into saturated aqueous ammonium chloride, diluted with water and extracted with ethyl acetate. The combined organic extracts were washed with brine, dried (sodium sulfate) and concentrated in vacuo. Purification by chromatotron using a 2 mm silica plate eluted with 95:5 chloroform/methanol gave the desired product as a pale yellow solid (36 mg). MS, m/z(M+)=471.2272.
