Participants

Reaction Steps

##STR39## To a solution of 3-chloropropyl 3-hydroxybenzoate (12.0 g, 0.055 mol) and tert-butyldimethylsilyl chloride (TBDMS-Cl, 10.00 g, 0.067 mol) in anhydrous DMF (10 mL) was added imidazole (7.61 g, 0.11 mol). The reaction mixture was stirred for 1 hour after which it was diluted with water (50 mL) and extracted with hexane (4×20 mL). The hexane layer was washed with water (2×10 mL) and dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give the desired compound (16.64 g, 0.0506 mol, 90%): 1H NMR (CDCl3) δ 0.216 (s, 6H), 0.994 (s, 9H), 2.19-2.27 (m, 2H), 3.69 (t, 2H, J=6.3 Hz), 4.46 (t, 2H, J=6.3 Hz), 7.01-7.64 (m, 4H); MS exact mass; calcd. 328.1264, found 328.1257.
