A portion of nginx.conf:

server {
listen 80;
server_name site2.example.com;

access_log /var/log/nginx/access.log;

location / {
proxy_pass http://site1.example.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
}

Unfortunately, when I try to access site2.example.com, nginx doesn't proxy to site1 URI. Instead it proxies to the IP address site1.example.com resolves to (or at least so it seems). Since site1 is a virtual host I get IIS welcome screen instead of site1 main page.

Any solution?

I would check the DNS records for both first,

dig A site1.example.com
dig A site2.example.com

I assume site1 is not local to the nginx server?

Resolving works for both hosts if you mean this. And yes, site 1 isn't local, it's on IIS on another server.

Also it works with server_name site1.example.com; and proxy_pass http://$host$uri; but this isn't exactly what I wanted to achieve.

What I mean is resolve it on the nginx box itself, I've seen it many times that people override entries with /etc/hosts tricks. Your nginx is supposed to look there first. But thats quite an interesting point you make there. I'm still not convinced it's not a resolving issue now.

How about trying it as such:

under http:

upstream ie_daemon {
server site1.example.com:80;
# [... up to the number of instance, or more, if you want to be free to add more ...]
}

Then under server (keep your server_name)

location / {
proxy_pass http://ie_daemon;

# include /etc/nginx/proxy.conf;
# my system doesn't have the proxy.conf file so I needed to add the following two lines to get redirects working:
proxy_redirect default;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

Remember, check resolving from inside and outside the server network to be sure it all matches up. I learned to always check the basics over and over again, saves me so much time.

Good luck
