Reaction Steps
N-Phenylpiperazine (1.3 ml, 8.51 mmol) is added to a mixture of 5-bromofuran-2-carbonyl chloride (1.5 g, 7.16 mmol), piperidinomethylpolystyrene (2.2 g, 3.5 mmol/g, 7.7 mmol) in anhydrous dichloromethane (30 mL) and stirred for 2.5 hr. The reaction mixture is diluted with dichloromethane and filtered through silica gel. The filtrate is concentrated to afford (5-bromo-furan-2-yl)-(4-phenyl-piperazin-1-yl)-methanone as a white solid (1.85 g, 77% yield); MS: m/e=336 (M+H). 1H-NMR (CDCl3, δ ppm) 7.03 (m, 6H); 6.45 (d, 1H); 3.96 (s, 4H); 3.28 (m, 4H).
