Procedure

10% Metallic hydrogen chloride (1.4 mL) was added to the solution of (2E)-3-(2-{[1-(4-chlorobenzoyl)-3-pyrrolidinyl]amino}-1,3-thiazol-4-yl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (0.6 g) in MeOH (12 ml) and the mixture was stirred at ambient temperature for 3.5 hours. To the reaction mixture was added ethyl ether and isolated precipitate was collected by filtration to give (2E)-3-(2-{[1-(4-chlorobenzoyl)-3-pyrrolidinyl]amino}-1,3-thiazol-4-yl)-N-hydroxyacrylamide hydrochloride (0.42 g)
