Procedure

Ethyl 2-(6-(cyclopropylmethoxy)-5-nitro-4′-(trifluoromethyl)biphenyl-3-yl)-4-methylpentanoate (100 mg, 0.208 mmol) was taken in a mixture of MeOH; THF:Water (30 ml, 10:10:2) and to it added LiOH (30 mg, 0.7 mmol). The reaction mixture was stirred at room temperature for 3 h. After completion of the reaction, it was poured into water (50 ml) and extracted with ethyl acetate (100 ml×2). The ethyl acetate layer was washed with 1N HCl, water and finally brine solution. The organic layer was then distilled off and the crude residue was purified by column chromatography using Ethyl acetate:hexane (1:1) as eluent provided 70 mg of 2-(6-(cyclopropylmethoxy)-5-nitro-4′-(trifluoromethyl)biphenyl-3-yl)-4-methylpentanoic acid. 1H NMR (CDCl3): δ 8.20 (s 1H), 7.40-7.20 (m, 5H), 3.60 (t, 1H), 3.45(d, 2H), 1.95-2.00 (m, 1H), 1.75-1.80(m, 1H), 1.45-1.50 (m,1H), 1.00 (m,6H), 0.35-0.25 (m,5H). Mass: (452, M+1, 100%).
