Reaction Steps

(S)-tert-Butyl 4-(1-amino-3-(4′-(4-methylpiperazin-1-ylsulfonyl)biphenyl-4-yl)-1-oxopropan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 29, step (i), 267 mg) in dichloromethane (10 mL) was treated with Burgess' reagent (202 mg) and the mixture was stirred at room temperature for 18 h. The solvent was partially evaporated under reduced pressure and the mixture was purified by chromatography on silica eluting with methanol/dichloromethane (0:100 to 5:95), triethylamine/methanol/dichloromethane (1:5:95) to afford the sub-titled compound (250 mg).
