Versuchsvorschrift

Molecular sieve, type 3A, (1 g) and benzo[1,2,5]thiadiazol-5-carbaldehyde (0.066 g, 0.4 mmol) were added to a solution of 4-amino-1-[2-(6-methoxy-quinazolin-4-yl)-ethyl]-cyclohexanol (0.116 g, 0.38 mmol) in methanol (1 ml) and dichloroethane (3 ml). The reaction mixture was stirred at room temperature for 20 hours and sodium triacetoxyborohydride (0.22 g, 1.04 mmol) was added. The reaction mixture was stirred at room temperature for 2 hours and then filtered over Hydromatrix (wetted with an NaHCO3 solution, 2 ml) and subsequently washed with dichloromethane. The filtrate was concentrated to dryness by rotary evaporation. The residue was purified by column chromatography on silica gel (dichloromethane/MeOH 9/1 1% NH4OH).
