• N-[(7,7a-dihydroisoquinolino[2,1-a]perimidin-13-yl)methyl]-N-isopropylpropan-2-amine obtained via a multi-step process

• 2-[(2-bromophenyl)ethynyl]benzaldehyde
• 2-[(2-bromo-5-fluorophenyl)ethynyl]benzaldehyde
• 2-[(2-bromo-5-methylphenyl)ethynyl]benzaldehyde
• 2-(phenylethynyl)benzaldehyde
• 2-[(4-methylphenyl)ethynyl]benzaldehyde
