Reaction Steps

A solution of 1,2-bis-bromomethyl-3-fluoro-benzene (4.4 g, 15.6 mmol) in MeCN (10 ml) was added to stirred solution of 1-cyclopent-1-enyl-pyrrolidine (2.3 ml, 15.6 mmol) and DIPEA (5.4 ml, 31.2 mmol) in MeCN (20 ml). The mixture was stirred at room temperature for 18 hours and then filtered. Washing with cold MeCN afforded an off-white solid 1.02 g (19%). m/z 258 (M+).
