Try either "\s1[A-Za-z]" if the "space" could be any whitespace character, or " 1[A-Za-z]" if it has to be a literal space character.

Demo[^]

If you want to get fancy, and match each 1 which is preceded by a space and followed by a letter, without capturing the space and the letter, then you'll need zero-width assertions. Eg: "(?<=\s)1(?=[A-Za-z])"

Demo[^]

If that still doesn't work, you'll need to specify which regex "flavour" you're using - PHP, JavaScript, .NET, etc. - and provide more precise details of what you have tried and what the problem is.
