Reaction Steps

To a solution of 2-pyrrolidinone (0.1 ml) in tetrahydrofurane (2 ml) sodium hydride (20 mg, 60% dispersion in mineral oil) was added. The reaction mixture was stirred at ambient temperature until the gas evolution ceased then 3-bromomethyl-1-oxo-2-phenyl-1,2-dihydro-isoquinoline-4-carboxylic acid ((S)-1-phenyl-propyl)-amide (30 mg) was added. After 30 min acetic acid (0.05 ml) was added and volatiles were removed in vacuo. The product was purified by flash chromatography on SiO2 (5 g, 1,2-dichloroethane then gradient 50% to 100% ethyl acetate in heptane) to give 17 mg of white solid. Yield 56%. LC-MS (m/z) 480.5 (MH+); tR=1.21.
