Procedure

To a solution of Step 1 intermediate from Intermediate 10 (400 mg, 2.712 mmol) in DMF (4 ml) was added 1,1,1-trifluoro-2-iodoethane (1.131 g, 5.413 mmol) at room temperature followed by Cs2CO3 (2.63 g, 8.120 mmol) and the reaction temperature was heated to 80° C. for 15.0 h overnight. The reaction mixture was diluted with ethyl acetate, washed with water and brine and purified by column chromatography using 1% methanol in chloroform to afford the desired compound; 1H NMR (300 MHz, CDCl3) δ 2.17 (s, 3H), 4.79 (q, J=9.3 Hz, 2H), 7.07-7.10 (m, 2H), 7.24-7.27 (m, 2H), 7.50 (d, J=4.8 Hz, 1H), 7.98 (d, J=4.5 Hz, 1H).
