Compound 12 was synthesized from ketone 5 (1 mmol) and cyclopentyl magnesium bromide (2 mmol) using procedure B described for synthesis of 6. The THP protection group was cleaved under the acidic conditions used. Yield: 18 mg (16%). 1H-NMR (400 MHz, CDCl3): δ ppm 7.26-7.14 (m, 1H), 7.13-7.12 (m, 2H), 6.89-6.85 (m, 2H), 6.76-6.73 (m, 2H), 4.75 (s, 1H), 2.50 (broad t, J=6.4 Hz, 2H), 2.13 (broad t, J=6.4 Hz, 2H), 1.75-1.58 (m, 4H).
