Participants

Reaction Steps

A solution of Intermediate 3 (50 mg) and sodium (triacetoxy)borohydride (106 mg) in dichloromethane (6 ml) and acetic acid (1 ml) was treated with 2-nitro-benzaldehyde (45 mg). The resulting mixture was stirred under nitrogen for 18 h. Saturated sodium bicarbonate solution was carefully added, and the mixture extracted with dichloromethane. The organic layer was passed through a hydrophobic frit, and evaporated. The residue was then purified on a silica gel SPE cartridge. Gradient elution with 10-18% ethyl acetate in petrol gave the title compound as a colourless solid (33 mg) LC/MS RT=4.83 min Found ES+=387
