To a 60-mL microwave vial was suspended (1R,3R)-methyl 1-(benzyloxycarbonylamino)-3-(4-bromophenyl)cyclopentanecarboxylate (1.1 g, 2.54 mmol) and 4,4,5,5-tetramethyl-2-vinyl-1,3,2-dioxaborolane (0.431 g, 2.80 mmol) and Cs2CO3 (2.487 g, 7.63 mmol) in DME (30 ml) and Water (7.50 ml). The reaction vessel was purged with nitrogen for 5 minutes. PdCl2(dppf) (0.186 g, 0.254 mmol) was added and the reaction vessel was purged with nitrogen one more time. The reaction mixture was heated to 120° C. in microwave for 30 minutes. The product ((1R,3R)-methyl 1-(benzyloxycarbonylamino)-3-(4-vinylphenyl)cyclopentanecarboxylate (705 mg, 1.858 mmol, 73.0% yield)) was isolated by FCC as a lightly colored oil.
