"syntax error before '@' token" on NSDictionary in command-line utility

Hi - I'm playing around with building a command-line utility in XCode. However, when I attempt to initialize an NSDictionary I get the following error:

"syntax error before '@' token".

Here's the code:

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:@”red”, @”color1”, nil];

[pool drain];
return 0;
}

The NSDictionary code is identical to example code provided in the XCode docs, and to other code snippets I've found on the web. So, I'm pretty confident that it's not a code problem...

Maybe it's my setup in XCode??
XCode version: 3.1.4
SDK: Mac OSX 10.5 (SDK Base)
Active Configuration: Debug
Under "Targets" > "Link Binary With Libraries" > Foundation.framework > Headers (includes NSDictionary.h)

I downloaded the iPhone SDK (I'm learning iPhone development). Could it be that I can't compile to Mac OSX with a command-line utility with just the iPhone SDK?

Any other ideas?

Thanks in advance!
