Participants

Reaction Steps

To a suspension of 2-({4-[2-(heptylamino)ethyl]-1,3-thiazol-2-yl}thio)-2-methylpropionic acid resin (0.15 g) synthesized in Example 461-6 in acetonitrile (1.5 ml) were added triethylamine (0.16 ml) and 2-chloro-3-nitropyridine (0.089 g), and the mixture was stirred at room temperature overnight. The resin was collected by filtration from the mixture, washed three times with dimethylformamide, tetrahydrofuran and methanol, and vacuum dried. Trifluoroacetic acid (2.0 mL) was added to the obtained resin, and the mixture was left standing at room temperature for 2 hr. Then the resin was removed by filtration from the reaction mixture, and the filtrate was concentrated by blowing a nitrogen gas, vacuum dried, and purified by preparative HPLC to give the title compound (1.5 mg) as a pale-brown oil.
