Reaktionsschritte

After 10 min. stirring sodium triacetoxyborohydride (11 mg, 0.05 mmol) was added to trans-7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepine-1-amine (10 mg, 0.03 mmol) and isobutyraldehyde (3.45 mg, 0.03 mmol) in 1 mL of CH2Cl2 (pH=4). The resulting mixture was stirred at room temperature for 18 h. The mixture was evaporated and chromatographed on silica. Elution with CH2Cl2/methanol 8:2 gave trans-N-(2-methylpropyl)-7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepine-1-amine (13 mg, 100%). Data: (m/z)=357 (M+H)+.
