Reaction Steps
3-{4-[(4-Aminophenethyl)oxy]phenyl}-2-ethoxypropanoic acid (20 mg, 0.061 mmol) and tert-butyl-[(tert-butoxycarbonyl)amino](methylsulfanyl)methylidenecarbamate (18.6 mg, 0.064 mmol) were mixed in 0.3 ml DMF. Triethylamine (25.5 ml, 0.183 mmol) was added. The mixture was then cooled in an ice-bath. Mercury (II)chloride (18 mg, 0.066 mmol) was added. After 30 minutes, the cooling bath was removed. The reaction mixture was stirred overnight. Water (1 ml) and ethyl acetate (0.5 ml) were added and then hydromatrix (ca. 0.5 g) was added. After a while, the mixture was filtered. The filtrate was evaporated to dryness. Chromatography of the residue on an ISOLUTE column (SI, 500 mg/3 ml) using ethyl acetate/heptane (10:90, then 25:75, and then 50:50) as eluant gave 15.4 mg, yield 44% of the desired product.
