Procedure

0.8 ml of a 7M HCl solution in isopropanol was added dropwise to a magnetically stirred solution of timolol (1.4 g) in isopropanol (30 ml). The solution was stirred for 30 minutes. The reaction mixture was freed of the solvent at reduced pressure. 1.47 g of pure product was obtained (yield 91%).
