This answer is not correct. You have the nitrogen electron pair attacking the methylsodium in an S_N2 reaction. Always think about the character of the reactants...atoms attached to metals always have negative character! The carbon atom of methylsodium has virtually a full negative charge and is not attractive to nucleophiles. In fact, it is the best nucleophile (base) in the reaction mixture. Now think about the character of the ethanolamine. What atoms have positive character and which atom will react with the one mole of methylsodium?
