Triethylamine → {[2-(Tert-butoxycarbonyl-methyl-amino)-acetyl]-methyl-amino}-acetic acid 1-{4-[2-(2-hydroxy-phenyl)-7-methyl-quinazolin-4-yl]-piperazine-1-carbonyl}-3-methyl-butyl ester

Participants

Reaction Steps

The amine was taken up in 1 mL CH2Cl2 and treated with 2-(4-chloro-7-methyl-quinazolin-2-yl)-phenol (53 mg, 0.19 mmol) and 49 μL of triethylamine, and stirred at room temperature for 3 h. The reaction mixture was diluted with 10 mL of CH2Cl2 and 10 mL of water. The organic layer was separated and dried over Na2SO4, and the solvent was removed under reduced pressure to give {[2-(tert-butoxycarbonyl-methyl-amino)-acetyl]-methyl-amino}-acetic acid 1-{4-[2-(2-hydroxy-phenyl)-7-methyl-quinazolin-4-yl]-piperazine-1-carbonyl}-3-methyl-butyl ester. LC/MS: m/z 677.4 (M+H)+ at 3.25 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
