Participants

Reaction Steps

In a 10 mL flask were added C-(3-chloropyrazin-2-yl)-C-(4-phenoxyphenyl)-methylamine (110 mg, 0.35 mmol), cyclohexanecarboxylic acid (0.090 g, 0.00070 mol), DIEA (0.55 mL, 0.0032 mol), TBTU (0.17 g, 0.00053 mol) and DMF (5 mL, 0.07 mol) and the reaction mixture is stirred at rt for 10 min. Reaction mixture was stirred at rt over weekend. The reaction mixture was concentrated in vacuo dissolved in DCM and washed with sat. aq NaHCO3 followed by brine. The organics were collected and concentrated in vacuo to give 160 mg of the compound as a yellow solid. Purification by prep TLC in 60% EtOAc:hexanes afforded 110 mg of the title compound as a light yellow solid. Compound was carried on to the next step. MS(ES+): m/z 422.15 (100)[MH+]. HPLC: tR=3.97 min (Open Lynx, polar—5 min).
