Reaction Conditions

Reaction Steps

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%).
