Procedure

A stirred suspension of tert-butyl 16-oxo-15-prop-2-yn-1-yl-6,15-diazadispiro[4.2.6.2]hexadecane-6-carboxylate (110 mg, 0.294 mmol, described in Intermediate 23), (2R)-5-iodo-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one (106 mg, 0.294 mmol, described in Intermediate 27), tetrakis(triphenylphosphine)palladium(0) (34 mg, 0.029 mmol), copper(I)iodide (23 mg, 0.121 mmol), and triethylamine (0.082 mL, 0.588 mmol) in degassed DMF (1.5 mL) was heated at 50° C. for 30 min. The reaction was quenched with water (30 mL), partitioned with saturated NaHCO3 solution (30 mL) and extracted with EtOAc (2×60 mL). The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified on silica gel, eluting with a gradient of CH2Cl2:MeOH—100:0 to 90:10, to yield the title compound. MS: m/z=609 (M+1).
