A safer butyl lithium quench:
Slowly add the butyl lithium ( using a double tipped needle with nitrogen  
pressure) to crushed dry ice. The butyl group adds to CO2 and forms the lithium  
salt of pentanoic acid. The dry ice also keeps everything very cold.
When adding butyl lithium to alcohol, butane is formed along with lots of  
heat. You are setting yourself up for a  fire/explosion.
