YieldReaction ConditionsOperation in experiment
48% With phosphorus tribromide; In dichloromethane; at 0 - 20℃; for 0.5h; General procedure: To a stirred solution of 18-4B (1.2 g, 6.6 mmol) in DCM, was added phosphorous tribromide (0.64 mL, 6.6 mmol) at 0 C and stirred to RT for 30 min. After consumption of the starting material (by TLC), reaction was quenched with saturated NaHC03 solution and extracted with DCM. The organic layer was dried over Na2S04, and concentrated under reduced pressure. The crude compound was purified by flash column chromatography (100-200 silica) using 5% EtOAc in hexane to afford 18-5B (0.95 g, 3.9 mmol, 59% yield) as a colorless semi-solid. adapted using 18-4A (1.42 g, 7.88 mmol) to prepare 18-5A (920 mg, 48%).
(ii) Oxalyl chloride (2.3 ml) was added to a solution of compound (B) (3.9 g) and DMF (0.3 ml) in dry dichloromethane (100 ml) and the mixture was stirred for 3 hours. The solvent and excess oxalyl chloride were removed by evaporation and dry methanol (50 ml) was added to the residue. The mixture was then stirred for 2 hours and the solvent removed by evaporation. The residue was partitioned between dichloromethane and aqueous sodium bicarbonate solution. The organic layer was separated, dried (MgSO4) and evaporated. The residue was triturated with a mixture of hexane and ether to give methyl 4-bromomethyl-2-methylbenzoate (C) (3.51 g) as a white solid, m.p. 51-53 C.; NMR (CDCl3): 2.59 (s, 3H), 3.89 (s, 3H), 4.44(s, 2H), 7.2-7.3(complex m, 2H), 7.88(d, 1H).
Addition of hot petrol and filtration from the phthalide gave after evaporation the title compound. tau(CDCl3) 7.48 (3H, s), 6.21 (3H, s), 5.65 (2H, s), 2.6-2.93 (2H, m), 2.18 (1H, d, J=8 Hz).
