If your sister-in-law is your spouse's sister, her brother is your spouse's brother and therefore is your brother-in-law, or perhaps your husband.

If your sister-in-law is the wife of your brother, her brother is your brother's brother-in-law but is not related to you. The English language has no relationship term for the brother of your sibling's spouse.
