Reaction Steps
To a solution of piperidine-1,4-dicarboxylic acid mono-tert-butyl ester (14.1 g, 0.061 mol) in DMF (282 mL) was added HBTU (27.76 g, 0.073 mol), DMAP (10.2 g, 0.084 mol) and diisopropylethyl amine (24.2 mL). The reaction mixture was stirred for 30 minutes at rt before 3,4-diaminobenzonitrile (8 g, 0.059 mol) was added. The mixture was stirred overnight at rt before the reaction was quenched by pouring into water (2 L). The mixture was extracted with CH2Cl2 and the organic phase washed successively with 1M aq. HCl solution and 10% aq. Na2CO3 solution, dried (Na2SO4) and concentrated in vacuo. Purification by chromatography on silica gel afforded the title compound.
