Draw the structure of the compound formed when alanine reacts with methanol in the presence of a small amount of concentrated sulfuric acid.

I know that the methanol reacts with the carboxylic acid to form cooch3. shouldnt the sulfuric acid react with the nh2 to form nh3+?

But surely it would have said in the side notes/exam report that they accepted nh3+
Btw, which exam board was this?
