Ethanol → Tert-butyl 4-(2-ethoxy-1-(6-(4-methylthiazol-2-ylamino)-5-phenoxypyridin-3-ylthio)-2-oxoethyl)piperidine-1-carboxylate

Participants

Reaction Steps

Placed methyl 3-(6-(4-methylthiazol-2-ylamino)-5-phenoxypyridin-3-ylthio)propanoate (2.20 g, 5.48 mmol), tert-butyl 4-(2,2,2-trichloro-1-hydroxyethyl)piperidine-1-carboxylate (1.86 g, 5.59 mmol), and sodium ethanolate (3.55 g, 10.9 mmol) in ethanol (75 mL) and stirred at ambient temperature for 4 hours. The reaction was quenched with sat NH4Cl and extracted with CH2Cl2. The organic phase was concentrated and purified by silica gel (10-25% EtOAc in hex) to give the title compound (2.63 g, 75.5% yield).
