1. Form a five membered isoxazoline ring numbered C1-N2-O3-C4-C5, with a double bond between C1 and N2.
2. At C1, attach a phenyl substituent whose benzene ring is 1 bromo 3,4 dimethoxy substituted; specifically, number the benzene ring so that the carbon bearing the bromine is position 1, the carbons at positions 3 and 4 each have a methoxy group, and the carbon bonded to C1 of the isoxazoline is position 6.
3. C4 carries two substituents: a methyl group and a carboxylic acid (-COOH).
