Procedure
Following general procedure B2 and D1, 3-(2,4-Dimethoxy-benzyloxy)-1H-benzo[4,5]thieno[3,2-d]pyrimidine-2,4-dione (50 mg, 0.13 mmol) was alkylated with 4-tert-butyl benzyl bromide and subsequently deprotected to provide the title compound as a white solid (ret.=3.32 min., m/z=381.0): 1H NMR (d6-DMSO, 300 MHz) δ 1.20 (s, 9H); 5.64 (s, 2H); 7.17 (d, J=8 Hz, 1H); 7.25-7.60 (m, 5H); 7.95 (d, J=8 Hz, 1H); 8.08 (d, J=8 Hz, 1H).
