Reaction Steps

2-amino-5,7-dihydro-4H-thieno[2,3-c]pyran-3-carboxamide (40 mg, 0.20 mmol) and 2-(3-(trifluoromethyl)-4,5,6,7-tetrahydroindazole-1-yl)acetic acid (50 mg, 0.20 mmol) were dissolved in DCM/DMF (3 mL/50 μL) and polymer supported carbonyldiimidazole (330 mg, 1.2 mmol/g, 0.396 mmol) added. The reaction mixture was heated at 120° C. for 10 min in the microwave. The reaction mixture was filtered washing with MeOH (10 mL), EtOAc (10 mL), and MeCN (10 mL). The filtrate was concentrated in vacuo to give a yellow gum. Purification by preparative reverse phase HPLC gave desired product as a white solid (7.6 mg, 0.018 mmol, 9%).
