実験手順: A mixture of 3-(2,6-dichlorophenyl)-3-oxopropanenitrile (0.200 g, 0.93 mmol), acetic anhydride (0.22 g, 2.20 mmol), and triethyl orthoformate (0.21 g, 1.40 mmol) was stirred at 150° C. for 1 hr. The solution was then concentrated and the residue redissolved in ethanol (5 mL). 4-heptylamine (0.16 g, 1.4 mmol) in 1 mL of tetrahydrofuran was added to the reaction mixture at 0° C. The reaction stirred for 30 minutes and was then concentrated. Flash chromatography (20% Ethyl acetate/hexanes) gave the desired compound (0.033 g, 10%). The solution was then concentrated the residue redissolved in ethanol (5 mL) The reaction stirred for 30 minutes was then concentrated

実験手順: n-Butyl lithium (20.1 mL, 32.2 mmol, 1.6M in hexanes) was added to THF (30 mL) and the solution was cooled to −78° C. Acetonitrile (1.7 mL, 32 mmol) was added dropwise and the reaction stirred at the temperature for 45 minutes. Methyl 2,6-dichlorobenzoate (1.00 g, 4.88 mmol) was dissolved in 2 mL THF and added to the reaction mixture. The reaction stirred at −78° C. for 0.5 hr. The solution was quenched with methanol and warmed to room temperature. The material was diluted with water and 1N HCl. The solution was then extracted with Ethyl acetate, dried, and concentrated to give 1.08 g of desired product at 85% purity. Material used as is in the next step. added to the reaction mixture The reaction stirred at −78° C. for 0.5 hr The solution was quenched with methanol warmed to room temperature The material was diluted with water and 1N HCl The solution was then extracted with Ethyl acetate dried concentrated
