Procedure
To a solution of 2-fluoroaniline (22.06 g, 0.198 mol) and freshly distilled tert-butyl acrylate (25.45 g, 0.198 mol) in dry benzene (250 ml) was added tin tetrachloride (1 ml) and the mixture was refluxed for 60 h. The resulting suspension was filtered and the filtrate was evaporated to give a semisolid which was chromatographed on silica gel eluting with 25/75 ethyl acetate/hexane to give the title compound (5.4 g, 11%). Anal calcd for C13H18NO2F: C, 65.25; H, 7.58; N, 5.85. Found: C, 65.49; H, 7.75; N, 5.80.
