YieldReaction ConditionsOperation in experiment
95% Step E; To a suspension of NaH (7.8 g, 200 mmol) in tetrahydrofuran (100 mL) under nitrogen was added dropwise a solution of <strong>[42726-73-8]tert-butyl methyl malonate</strong> (20 mL, 120 mmol) in anhydrous tetrahydrofuran (100 mL) via syringe. The reaction mixture was stirred for 0.5 h before a solution of the intermediate prepared in Step D, Intermediate 8 (20.1 g, 97.6 mmol) in tetrahydrofuran (200 mL) was added slowly via syringe. The reaction was stirred at room temperature overnight, then quenched with a saturated solution of NHtCl. The organic layer was separated and the aqueous layer was extracted with ethyl acetate (3 x). The combined organic layers were washed with water (3 x), dried over Na2S04, filtered, and evaporated i71 vacuo. Flash chromatography afforded 31.76 g (95percent) of the pure desired product. 1H NMR (500 MHz, CDCl3) 8 9.03 (d, J=1.5 Hz, 1H), 8.25 (d, J=2.0 Hz, 1H), 5.25 (s, 1H), 3.86 (s, 3H), 1.52 (s, 9H).

94.6% To a suspension of NaH (7.8 g, 200 mmol) in THF (100 mL) under nitrogen was added dropwise a solution of <strong>[42726-73-8]tert-butyl methyl malonate</strong> (20 mL, 120 mmol) in anhydrous THF (100 mL) via syringe. The reaction mixture was stirred for 0.5 h before a solution of the intermediate prepared in Step D (20.1 g, 97.6 mmol) in THF (200 mL) was added slowly via syringe. The reaction was stirred at room temperature overnight, then quenched with a saturated solution of NH4Cl. The organic layer was separated and the aqueous layer extracted with ethyl acetate (3.x.). The combined organic layers were washed with water (3.x.), dried over Na2SO4, filtered, and evaporated in vacuo. Flash chromatography afforded 31.76 g (94.6percent) of the pure desired product. 1H NMR (500 MHz, CDCl3) delta 9.03 (d, J=1.5 Hz, 1H), 8.25 (d, J=2.0 Hz, 1H), 5.25 (s, 1H), 3.86 (s, 3H), 1.52 (s, 9H).
84% To a suspension of sodium hydride (0.752 g, 29.8 mmol) in THF (18 mL) under nitrogen was added dropwise a solution of <strong>[42726-73-8]tert-butyl methyl malonate</strong> (3.18 mL, 17.9 mmol) in dry THF (15 mL) via syringe during a period of 15 min. The reaction mixture was stirred for 30 min before a solution of 2-chloro-5-(trifluoromethyl)nicotinonitrile (4.0 g, 14.5 mmol) in THF (30 mL) was added slowly. After being stirred at room temperature overnight, the reaction mixture was quenched with aqueous NH4Cl. THF was removed in vacuo and the aqueous solution was extracted with EtOAc three times. The combined organic layers were dried over MgSO4, filtered, and evaporated in vacuo. The crude brown product (7.1 g) was purified by flash chromatography (10:90 EtOAc/hexanes) to afford 4.20 g (84percent) of desired product as a yellow oil. LC-MS calculated for C15H15F3N2O4: (M+H)+345; found 245.0 (M-CO2tBu+H+1)+.
