Click the Send to button and select Citation manager from the drop-down menu
A new dialog box opens. Click on the Create file button then save the file on your computer (you can delete this file after the references are imported to EndNote.
Now that the references are downloaded, you can import them into EndNote. In EndNote, click the Collect tab and select Import References
Click the Choose File button and browse your computer for the saved file
In the Import Option drop-down menu, select PubMed (NLM)
Note: You can add Import Options to a list of your favorites so you don't have to keep searching for the options you use most frequently. When you click on Select Favorites, find the option you want and then click on Copy to Favorites.
In the To: drop-down menu, you must select a group, create a new group, or select [Unfiled]. If you create a new group, you can name the group after you click Import
