Thieno[2,3-d]pyrimidine-6-carbaldehyde (intermediate 13) (40 mg), 3,4-dimethoxybenzylamine (0.04 ml) and 4 Å molecular sieves (150 mg) were heated at reflux in DCM (5 ml) for 3 hours under an inert atmosphere. The molecular sieves were removed by filtration and the solvent evaporated to afford the title compound as a pale yellow solid (76 mg, 100%);
