Reaction Steps

To 5-bromosalicylaldehyde (15.0 g, 74 mmol) in dimethylformamide was added anhydrous potassium carbonate (36.8 g, 266 mmol) and bromomethylcyclopropane (9 ml, 93 mmol) and the solution stirred at 50 ° C. for 60 hours. Propylamine (26.5 g, 450 mmol) was then added and the solution left to stir at ambient temperatures for 2 hours, after which diethyl ether (50 ml) and sodium borohydride (2.6 g, 68 mmol) were added and the solution left for another hour. 6 Normal hydrochloric acid (150 ml) was then added dropwise and the solution left to stir for 16 hours. Impurities were extracted with diethyl ether (200 ml×2), the solution basified with caustic liquor and the product then extracted into diethyl ether (250 ml). The organic layer was then dried over anhydrous magnesium sulphate, filtered and the solvent removed in vacuo to give the title compound (4.8 g, 22%).
