The mixture was cooled to RT, and solvents were then evaporated. To the resulting crude product 3 was added hydrazine mono-hydrobromide (3.0 equiv.), 200 proof EtOH (1.0 mL), and H2O (0.3 mL). The mixture was heated in a microwave reactor at 120 C for 20 minutes. The mixture was cooled to RT and concentrated in vacuo. The resulting residue was subjected to liquid-liquid extraction using saturated NaHCO3 (aq) and CH2Cl2. The organic layer was collected, dried over anhydrous MgSO4, filtered and removed under vacuum to afford 4.The resulting crude product 4 and 2-arylsubstitutedmalondialdehydes or 1,1,3,3tetramethoxypropane (1.0 equiv.) were dissolved in glacial AcOH (1.0 mL) and 200 proof EtOH (1.5 mL). The mixture was heated in a microwave reactor at 120 C for 20 minutes. After cooling on ice, the precipitate was collected on a fine scintered-glass frit and washed with icecold EtOH (2 x 1.0 mL). The resulting crystals 5-32 were dried and collected.
