Prop-2-en-1-yl 4-(bromomethyl)benzoate → HCID 19605229, compound

Participants

Reaction Steps

Allyl 4-(bromomethyl)benzoate (98 g, 0.4 moles) in dry dimethylformamide (100 ml) was added dropwise to a cooled suspension of potassium thioacetate (46 g, 0.4 moles) in dry dimethylformamide (200 ml). The cooling bath was removed and the mixture was stirred overnight. The reaction was poured into water and extracted with ethyl acetate (×3). The combined extracts were washed with water and brine. The mixture was dried and evaporated to give allyl 4-(acetylthiomethyl)benzoate as an orange oil (100 g, 100% yield). 1H NMR δ (CDCl3) 2.36 (3H, s, COCH3), 4.13 (2H, s, CH2), 4.82 (2H, m, CH2O), 5.32 (2H, m, CH2CH--), 6.05 (1H, m, CHCH2), 7.35 (2H, d, Ph-H), 7.98 (2H, d, Ph-H).
