Procedure
A solution of 1-{2-[(3S,4S)-3-(aminomethyl)-4-hydroxy-1-pyrrolidinyl]ethyl}-7-fluoro-2(1H)-quinolinone (100 mg; 0.33 mmol) and 3-oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]thiazine-6-carboxaldehyde (for a synthesis, see WO2004058144, Example 7(d) (64 mg, 0.33 mmol) in methanol (2 mL), DCM (4 mL) was stirred at room temperature overnight. Sodium triacetoxyborohydride (0.13 g; 0.6 mmol) was added and the mixture was stirred at room temperature for 1 hours. The reaction was evaporated and chromatographed on silica gel, eluting with 0-10% methanol-DCM-1% NH4OH to give an oil. The oil was treated with 1M HCl in Et2O to give the title compound (60 mg) as the dihydrochloride salt.
