Reaction Steps

A mixture of [(1S,2S)-1-({(4-bromo-phenyl)-[trans-2-(6-fluoro-pyridin-2-yl)-cyclopropanecarbonyl]-amino}-methyl)-2-methyl-butyl]-carbamic acid t-butyl ester (78 mg, 0.146 mmol), arylboronic acid (0.18 mmol), Pd(PPh3)2Cl2 (14 mg, 0.02 mmol) and K2CO3 (38 mg, 0.27 mmol) in CH3CN/H2O (3.5/0.5 mL) was heated in a microwave at 140° C. for 20 min. The reaction mixture was passed through a short silica pad (EtOAc) and concentrated. The residue was subjected to ISCO (12 g column, 0-50% EtOAc in hexane over 25 min) to give the desired products. MS (MH+ 576).
