Reaction Steps

To a solution of ethyl 2-(bromomethyl)-3-phenylcyclopropanecarboxylate (Preparation 26, 65 mg, 0.22 mmol) in N,N-dimethylformamide (2 ml) was added sodium hydrogen carbonate (30 mg, 0.36 mmol) and hexylamine (33 μl, 26 mg, 0.26 mmol), and the mixture was heated to 150° C. for 3 h. The mixture was cooled, water (30 ml) was added, and the mixture was extracted with diethyl ether (2×30 ml). The extracts were combined, dried (Na2SO4), filtered and concentrated in vacuo. The mixture was purified by silica column (5 g) chromatography eluting with 4:1 dichloromethane:ethyl acetate. Product-containing fractions were combined and concentrated in vacuo to give the title compound as a colourless oil (45 mg, 76%).
