I've found it's better to put the crate near you, so in the living room if you watch tv, etc. If you put the dog in a room far away from you where he can't see or hear you, it's like punishment to them. It helps if you're nearby when they're learning, so they can see it's ok to be there, it's not punishment.
I'd put him in there for a few minutes at a time at first. Give him a command like 'kennel up' and give him a treat when he goes in. Definitely give him some toys to chew on/play with. You can use a squirt bottle with water in it in case he barks or whines. When he's quiet, tell him good boy. After he settles down and is quiet, you can let him out and praise him. Keep doing that until he gets comfortable in there. Eventually he should get the hang of it.
