Ethylamine hydrochloride → N-(((1S,2S)-4'-(4-Chlorophenyl)-2',3',9'-trimethylspiro[cyclopropane-1,6'-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin]-2-yl)methyl)ethanamine

Reaction Steps

To a solution of (1S,2R)-2-(bromomethyl)-4′-(4-chlorophenyl)-2′,3′,9′-trimethylspiro-[cyclopropane-1,6′-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine](50 mg, 0.108 mmol) in anhydrous N,N-dimethylformamide (3 mL) were added ethanamine hydrochloride (221 mg, 2.71 mmol) and Hunig's base (473 μl, 2.71 mmol) at rt. After 4 days at rt, silica gel was added to the reaction, and the solvent was removed under vacuum. The dry silica gel was packed and the product was purified by chromatography (Hexane/EtOAc 5:5 to 0:10 then DCM/MeOH 10:0 to 9:1). A second chromatography was performed (2-propanol 100% then DCM/MeOH 9:1) to give a tan solid (32 mg). LRMS (M+H)+: 426 m/z.
