実験手順
N*1*-(8-Methoxy-2-methylquinolin-4-yl)-1-phenylethane-1,2-diamine (Example 75, 150 mg, 0.488 mmole) and benzaldehyde were stirred at RT for 20 hrs. Molecular sieve (4A) was added and the mixture was heated to 60° C. within 2 hrs. NaBH4 was added and the mixture was stirred for 1 h at RT. The resulting mixture was filtered and extracted with dichloromethane. The organic phases were dried and concentrated. The residue was purified using preparative HPLC (RP-18, water/acetonitrile) to obtain the product (21 mg, 11%).
