Hydrochloric Acid → HCID 68468429, compound

Participants

Reaction Steps

15.8 g (0.1 mol, 1.0 eq.) of 4-chlor-2,3-dimethylpyridine-N-oxide, 8.0 g (0.2 mol, 2.0 eq.) of caustic soda, and 23.2 g (0.2 mol, 2.0 eq.) of 1-heptanol were added to 64 mL of toluene, and the mixture was heated to reflux for 3 hours, and then cooled to room temperature. 15 mL of water was added to the reaction liquid, and then the mixture was neutralized with concentrated hydrochloric acid (8 mL). Subsequently, the resultant was extracted three times with 670 mL of chloroform. The extract was dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure, to obtain 37.3 g of 4-heptyloxy-2,3-dimethylpyridine-N-oxide as a black brown oily matter.
