Reaction Steps

step 2—A sealed tube containing 96 (100 mg, 0.25 mmol), 2-benzyloxy-pyridin-3-yl boronic acid (85 mg, 0.37 mmol), Na2CO3 (80 mg, 0.74 mmol) and Pd(PPh3)4 (29 mg, 0.025 mmol) in a mixture of MeOH (1.5 mL) and DCM (0.5 mL) was irradiated on a microwave synthesizer at 100° C. for 30 min. The reaction mixture was diluted with DCM, filtered through a pad of CELITE, and the filtrate was concentrated. The crude residue was purified on a preparative SiO2 TLC plate developed with 30% EtOAc/hexanes to afford 99 mg of 1-[2-(2-benzyloxy-pyridin-3-yl)-4-tert-butyl-5-methoxy-benzyl]-3-methyl-1,3-dihydro-benzoimidazol-2-one (98).
