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 7-chloro-3-oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine-6-carboxaldehyde (for a synthesis see WO2003064421, Example 15(c)) (70 mg, 0.33 mmol) in methanol (2 mL), methylene chloride (4 mL) was stirred at room temperature overnight. Sodium triacetoxyborohydride (130 mg; 0.6 mmol) was added and the mixture was stirred at room temperature for 1 hour. The reaction was evaporated and chromatographed on silica gel, eluting with 0-10% methanol-DCM-1% NH4OH to give the title compound as a solid (80 mg).
