Reaction Steps

This compound was prepared in a similar fashion as described in Example 80 starting from (8E)-8-[(dimethylamino)methylene]-4-[2-(4-nitrophenyl)ethoxy]-5,8-dihydro[1]benzothieno[2,3-d]pyrimidin-7(6H)-one (7.05 g, 16.61 mmol) and 2-tert-butyloxycarbonyl-2-hydroxyethylhydrazine (4.39 g, 24.91 mmol). The desired product was obtained as a yellow solid (3.82 g, 53%). 1H-NMR (DMSO-d6) δ 8.50 (s, 1H), 8.18 (m, 2H), 7.64 (m, 3H), 4.88 (m, 1H), 4.77 (t, 2H, J=6.1 Hz), 4.10 (t, 2H, J=5.5 Hz), 3.68 (m, 2H), 3.28 (m, 2H), 3.05 (m, 2H), 2.96 (m, 2H); LCMS RT=2.92 min; [M+H]+=438.1
