Participants

Reaction Steps

Starting material (3(b)) was synthesised as follows. A mixture of mono-methyl-5-nitroisophthalate (13.8 g), allyl bromide (7.96 g), potassium carbonate (13.94 g) and DMF (160 ml) was stirred at ambient temperature for 4.5 h. The solid was filtered and DMF was evaporated away from the filtrate under reduced pressure. The residue was dissolved in diethyl ether (300 ml) and water (100 ml) and stirred for five minutes. The organic layer was separated and washed with saturated sodium bicarbonate solution (220 ml), brine (200 ml). dried over magnesium sulphate and evaporated under reduced pressure to give 5-nitro-isophthalic acid allyl ester methyl ester (3(a)) as a yellow oil (14.74 g).
