hex-2-ynoic acid

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:75.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 2-(3-iodophenoxymethyl)-naphthalene (0.5 g, 1.4 mmol) and hexynoic acid (0.19 g, 1.7 mmol) in piperidine (5 mL) is purged with Argon for 20 minutes. Then bis(triphenylphosphine)palladium dichloride (0.01 g, 0.014 mmol) and cuprous iodide (0.005 g, 0.028 mmol) are added and this mixture heated in an oil bath at 75° C. for 1.5 hours and then allowed to come to room temperature overnight. The solvent was removed in vacuo and the residue purified by flash chromatography (silica, 4% methanol in dichloromethane) to give the title compound. 1H NMR (300 MHz, CDCl3) δ 7.83-7.88 (m, 4H), 7.48-7.54 (m, 3H), 7.19 (t, 1H), 6.98-7.05 (m, 3H), 5.21 (s, 2H), 2.47 (t, 2H), 1.80-1.91 (m, 4H); MS (EI) 344 (M)+.

Procedure: A solution of 2-hexynoic acid (5.03 g) and cyclopropylamine (2.70 g) in dichloromethane (75 ml), and a solution of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (9.00 g) and 1-hydroxybenzotriazole hydrate (7.19 g) in dichloromethane (75 ml) were mixed, and the mixture was stirred at room temperature for 18 hr. 1N Hydrochloric acid (200 ml) was added, and the mixture was extracted with dichloromethane. The organic layer was washed with 5% aqueous sodium hydrogen carbonate solution, water and saturated brine, dried over anhydrous magnesium sulfate, and purified by silica gel column to give the title compound (6.04 g, 89%). the mixture was extracted with dichloromethane The organic layer was washed with 5% aqueous sodium hydrogen carbonate solution, water and saturated brine dried over anhydrous magnesium sulfate purified by silica gel column
