Reaction Steps

0.117 g (0.85 mmol) of K2CO3 and N,N-diisopropylethylamine 0.072 g (0.56 mmol) followed by 0.201 g (0.85 mmol) of (3-bromo-propyl)-carbamic acid tert-butyl ester, dissolved in 5 ml of DMF, were added to a stirred solution of 0.373 g (0.85 mmol) of 2,6-bis-(4-cyano phenoxy)-N-piperidine-4-yl nicotinamide, dissolved in 5 ml of DMF over a period of 15 min at 20° C. Reaction mixture was allowed to attain RT and heated to 45° C. for 2 h. The reaction mixture was concentrated under reduced pressure to remove the solvent. The residue was partitioned between water (150 ml) and ethyl acetate (150 ml). The organic phase was washed with 1 M Na2CO3 and saturated brine solution, and dried over sodium sulphate. The solution was concentrated and the oily residue was purified by column chromatography using hexane-ethyl acetate (10:2) to afford 0.45 g of the required product. Percentage purity (LCMS): 72.5%, (M+1)=596.2+1.
