Reaction Steps

N-(4-Chlorobenzyl)-4-hydroxy-2-oxo-7-(3-(tetrahydro-2H-pyran-2-yloxy)-1-propynyl)-2H-pyrido[1,2-a]pyrimidine-3-carboxamide (Preparation 7, 12 mg) is dissolved in CH2Cl2 and treated with 0.5 M HCl in methanol (0.5 mL). The reaction mixture is stirred for 16 h at room temperature. The mixture is concentrated, and the residue is crystallized from ether/hexanes and dried to afford 7 mg of the title compound as a brown solid. Physical characteristics: 1H NMR (CD3OD) δ9.2, 8.35, 7.75, 7.4-7.5, 4.80, 4.50; MS (ESI+) m/z 386 (M+H)+.
