Participants

Reaction Steps

A mixture of (5S)-2-(trans-4-hydroxycyclohexyl)-2,7-diazaspiro[4.5]decan-1-one (20 mg, 0.00007 mol) which was prepared using procedures analogous to those described in the synthesis of example 472-a and followed by standard hydrogenation to remove the carbobenzyloxy (Cbz) protecting and, 4-methyl-2-fluoro-1-iodobenzene (21 mg, 0.00009 mol), sodium tert-butoxide (9.98 mg, 0.000104 mol), 1,4,7,10,13,16-hexaoxacyclooctadecane (27.4 mg, 0.000104 mol), 2-(di-tert-butylphosphino)biphenyl (0.8 mg, 0.000003 mol), tris(dibenzylideneacetone)dipalladium(0) (1 mg, 0.000001 mol), in tert-butyl alcohol (1.0 mL, 0.010 mol) was stirred at rt for 18. The crude product was purified by prep-HPLC to afford the desired product. LC-MS: 361.1 (M+H)+.
