Diisopropylethylamine → 1-(2-Amino-4,5,7,8-tetrahydro-thiazolo[4,5-d]azepin-6-yl)-2-(3,5-bis-(4-fluoro-phenyl)-(1,2,4)triazol-1-yl)-ethanone

Participants

Reaction Steps

350 mg (3,5-bis-(4-fluoro-phenyl)-(1,2,4)triazol-1-yl)-acetic acid and 0.2 mL DIPEA were dissolved in 4.5 mL DMF. 570 mg PFTU was added to this solution and the mixture was stirred for 7 min at RT. Then, 333 mg 5,6,7,8-tetrahydro-4H-thiazolo[4,5-d]azepin-2-ylamine dihydrobromide and 0.4 mL DIPEA were added and the reaction was stirred over night at RT. Then, sodium hydrogencarbonate solution (10%) and CH2Cl2 were added, the organic phase was separated and the solvent was removed. The residue was purified by HPLC to yield 252 mg of the desired compound.
