Trifluoroacetic acid → HCID 46853342, compound

Participants

Reaction Steps

90 mg (0.113 mmol) of 2-{4-(2-(azetidin-1-yl)-6-({(2-(4-chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-3,5-dicyanopyridin-4-yl)phenoxy}ethyl N-(tert-butoxycarbonyl)-beta-alanyl-L-alaninate (Example 4A) were initially charged in 3.5 ml of dichloromethane. 0.347 ml (4.502 mmol) of trifluoroacetic acid was added, and the reaction solution was then stirred at RT overnight. The reaction solution was concentrated by evaporation and the residue was purified by preparative HPLC (acetonitrile/water+0.1% TFA). For further purification, the product was once more purified by preparative HPLC (column material: XBridge; mobile phase: acetonitrile/0.1% aq. ammonia=65/35). This gave 51 mg (65% of theory) of the target compound.
