To a dry, stirred solution of 8.0 g of 2-amino-4-methylquinazoline in 200 ml of methylene chloride at ambient temperature and pressure is added 13 g of 2-chloropyridin-3-sulfonylisocyanate. The resulting mixture is stirred at reflux for 2 hours and then concentrated at reduced pressure. The residue is triturated with 1-chlorobutane and filtered to yield the desired solid product.
