Chloromethyl-dimethyl-4-fluorobenzylsilane (2.01 g, 9.33 mmol) and potassium phthalimide (1.90 g), 10.27 mmol) were heated in dry dimethylformamide (30 ml) at 70° C. for 5 hours and then the mixture was poured into water and extracted with ether. The ether solution was washed with water, brine, dried and evaporated. Chromatography (silica gel, ether/hexane-20/80) afforded N[(dimethyl-4-fluorobenzylsilyl)methyl]phthalimide as a white powder (2.90 g, 95% yield) 1H NMR (CDCl3, TMS) δ: 0.20 (s,6H), 2.25 (s,2H), 3.27 (s,2H), 6.83-7.13 (m,4H), 7.67-7.97 (m,4H).
