Reaction Steps

A 2 mL CH3CN suspension of 0.05 g (0.11 mmol) 8-(2-aminobenzyl)-4-(cyclohexylamino)-1-(3-fluorophenyl)-1,3,8-triazaspiro[4.5]dec-3-en-2-one (example 80), excess 4-bromobutyronitrile and Cs2CO3 was heated to 60° C. and allowed to stir for 2 days. HPLC/MS showed a small amount of product so the reaction was filtered and concentrated. The remaining oil was purified on an Isco automated system affixed with a Biotage Flash 25(M) cartridge eluted with 0-5% MeOH+0.5M NH3 in CH2Cl2 over 30 min at 20 mL/min. The product eluted last.
