Diisopropylethylamine → HCID 86653641、化合物

TBTU (3.22 mmol, 1.05 eq) is added to a solution of 2-amino-5-(3-fluoro-phenyl)-thiazole-4-carboxylic acid (3.07 mmol, 1.0 eq), N-[(1S,3S,5S)-2-aza-bicyclo[3.1.0]hex-3-ylmethyl]-2,2,2-trifluoro-acetamide (3.07 mmol, 1.0 eq) and DIPEA (9.20 mmol, 3.0 eq) in DCM (15 mL) and DMF (3.0 mL). After 2 h the mixture is washed twice with water, once with sat. aqueous NaHCO3 solution, once with hydrochloric acid (0.2 M) and three times with water. The organic layer is dried over Na2SO4, the solvents are removed in vacuo and the residue is purified by preparative TLC (DCM/MeOH 9/1) to give the desired product as an orange foam. LC-MS (acidic): tR=0.87 min; [M+H]+=429.1.
