Versuchsvorschrift

(R)-2-(3-Oxo-1-tosyl-1,2,3,4-tetrahydropyrazin-2-yl)acetic acid (140 mg) and (1R)-6-(1-(piperidin-1-yl)ethyl)-1,2,3,4-tetrahydronaphthalen-1-amine (122 mg, prepared in Example 12) are combined in 2 mL of DMF, then EDCI (112 mg) and HOBT (79 mg) are added and the mix is stirred under nitrogen overnight. Next the mix was quenched with sat. sodium bicarb., extracted with ethyl acetate, washed with brine, washed with water, dried with sodium sulfate, and concentrated. The compound was then purified on the varian using 10 to 90% acetonitrile in water to give the product. MS 551 (ESI, pos. ion).
