Procedure

Combine 3-(3-methyl-4-oxo-5H-2-oxa-1,5,7-triaza-cyclopenta[a]naphthalen-5-yl)-cyclohexanecarboxylic acid (50 mg, 0.15 mmol) with 1-[3-(dimethyl-amino)propyl]-3-ethylcarbodiimide hydrochloride (32 mg, 0.17 mmol), 1-hydroxy-7-azabenzo-triazole (23 mg, 0.17 mmol), N,N-diisopropylethyl amine (44 mg, 3.4 mmol) and 3,4,5-trimethoxy benzylamine (33 mg, 0.17 mmol) in N,N-dimethyl-formamide (4 mL) and stir overnight at ambient temperature. Concentrate in vacuo and take up in water and extract with dichloromethane. Dry the combined extracts over sodium sulfate. Concentrate and chromatograph over silica gel to give 66 mg (85%) of the desired product as a white solid. MS(ES): (M+1)+ 507.2, 508.2, 509.2 m/z.
