Reaction Steps
To a mixture of [1,3-bis(2,6-diisopropylphenyl)imidazolidin-2-yl](chloro)[(2,3-●)-(1Z)-1-phenylprop-1-ene-2,3-diyl]palladium(2+) (3.4 mg, 0.0000052 mol) and potassium tert-butoxide (32.0 mg, 0.000286 mol) under an atmosphere of argon was added 4-{[(1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)-cyclopentyl]oxy}-2-chloropyridine (0.1226 g, 0.0002596 mol) in 1.00 ml DME, followed by (1S)-5-chloro-3,3-dimethylindan-1-amine (0.048 g, 0.00025 mol) in 1 ml DME. The mixture was stirred overnight, and the solution was poured into 50 ml EtOAc, washed with 10 ml water and concentrated. The residue was purified by preparative plate chromatography (70% EtOAc/hexanes) to afford the title compound (28.0 mg, 18.0%).
