# What is the product of the reaction between alcohol and acetyl chloride in presence of pyridine?

What happens when butan-2-ol reacts(under heat) with $$\ce{CH3COCl}$$ in the presence of pyridine? Does it form $$\ce{CH3COOCH(CH3)CH2CH3}$$? I got the ester mentioned but the solution says it gives an alkene. What is the product when an alcohol reacts with an acid chloride in the presence of pyridine?

• How much pyridine and at what temperature? Jun 4 at 11:24
• These are standard acylation conditions for alcohols done at ice-bath or room temperature, so unless it is being heating strongly in the presence of a large excess of pyridine I doubt you're going to get an alkene. What is the source that says you will? Jun 4 at 12:22
• @Waylander The amount of pyridine is not mentioned but the the reaction proceeds under heating. Jun 4 at 13:01
• In what solvent at what temperature? Jun 4 at 14:00
