1,2-Dichloroethane → Benzoxazole-6-carboxylic acid (furan-2-ylmethyl)-amide

Participants

Reaction Steps

To solution of 2-(4-adamantan-1-yl-phenoxymethyl)-benzoxazole-6-carboxylic acid (30.1 mg, 0.08 mmol), furfuryl amine (11.0 mg, 0.12 mmol, 0.01 ml), EDC (21.7 mg, 0.12 mmol) and HOBt (15.4 mg, 0.12 mmol) in DMF 3.0 mL was added DIPEA (14.2 mg, 0.12 mmol, 0.02 ml). After stirring at room temperature, the mixture was partitioned between ethyl acetate and brine. The organic phase was dried (MgSO4 anh), and concentrated. The residue was purified by silica gel column chromatography (n-Hexane:EtOAc:MeOH=6:3:1) to give 2-adamantan-1-yl-phenoxymethyl)-benzoxazole-6-carboxylic acid (furan-2-ylmethyl)-amide as a white solid (6.3 mg, 17.4% yield).
