Electric Literature of 252881-74-6, A common heterocyclic compound, 252881-74-6, name is tert-Butyl 3-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)propanoate, molecular formula is C13H27NO5, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A solution of 25 mg of 3-(3-(4-(piperidin-1-yl)-2-(4-(3-(trifluoromethyl)-benzylcarbamoyl)pyridin-2-yl)phenylcarbamoyl)benzylthio)benzoic acid 8.1, 12 mg of tert-butyl 3-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)propanoate, and 17.8 mg of diisopropylethylamine in 1 mL of DMF was treated with 15 mg of HATU. The mixture was stirred for 1 h and then the product was isolated by reverse phase HPLC eluting with 0.05% TFA in a water/acetonitrile gradient.
The synthetic route of 252881-74-6 has been constantly updated, and we look forward to future research findings.
