Sodium Hydroxide → 6-Methoxy-4-(4,4,4-trifluoro-butyl)-isoquinoline

Participants

Reaction Steps

2 g 6-Methoxy-isoquinoline were dissolved in 25 mL of dry tetrahydrofuran. 12.56 mL of a 1 M solution of potassium triethyl borohydrate were added dropwise. The solution was allowed to stir at room temperature for 2 h, then 3.29 g of 4,4,4-Trifluoro-1-iodobutane were added dropwise. The solution was allowed to stir overnight, then 32 mL of 1M sodium hydroxide and 12 mL of sodium peroxide solution (35%) were added. Stirring was continued for another 3 hrs, then the solution was diluted with dichloromethane, extracted with water and brine and the organic layer was dried over sodium sulfate and evaporated to dryness. Silica gel chromatography yields 1.03 g of the desired product.
