Procedure

Neat diethyl malonate (19.07 mL, 125 mmol) was added slowly to a suspension of sodium hydride (60% in mineral oil, 5.52 g, 138 mmol) in dimethylacetamide under N2 atmosphere. The mixture was stirred at room temperature until the evolution of hydrogen gas ceased, then the mixture was heated to 90° C. for 30 min then cooled to room temperature. A solution of Compound 59 (39.88 g, 138 mmol) in dimethylacetamide was added slowly and the mixture heated overnight at 110° C. The mixture was cooled to room temperature, poured into ice water, and acidified by cold 10% HCl. The solids formed were filtered, washed several times by water, and dried at room temperature under vacuum to yield 38 g (86%) of white solids. 1H NMR (DMSO-d6): δ 1.31 (t, J=7.2 Hz, 3H), 4.32 (q, J=7.2 Hz, 2H), 5.45 (s, 2H), 7.17 (d, J=7.2 Hz, 2H), 7.2 (m, 2H), 7.31 (t, J=6.8 Hz, 1H), 7.37 (d, J=9.2 Hz, 1H), 7.65 (dd, J=2.8, 9.2 Hz, 1H), 8.02 (d, J=2.4 Hz, 1H), 12.90 (b, 1H); EIMS: 358 (M+H).
