Participants

Reaction Steps

A mixture of example 6 (51 mg), aqueous formaldehyde (33 μL) and sodium triacetoxyacetoxyborohydride (50 mg) in anhydrous 1,2-dichloroethane (2 mL) was stirred at r.t. overnight. The mixture was washed with water (2 mL) and brine (2 mL) and concentrated in vacuo. The residue was purified by flash chromatography (AcOEt 100%) to give 7-(R)-(4-fluoro-2-methyl-phenyl)-4-methyl-[1,4]-diazepane-1-carboxylic acid, (3,5-dichloro-benzyl)-methylamide (10 mg).
