Reaction Steps

To 20 ml vial was added 3-[(4-oxo-3H-phthalazin-1-yl)methyl]benzoic acid (1b) (50 mg, 0.178 mmol). To this was added N,N-dimethylacetamide (2 mL) and triethylamine (70 μL, 0.445 mmol). This mixture was allowed to stir for 5 mins before addition of O-benzotriazol-1-yl-N,N,N′,N′-tetra-methyluronium hexafluorophosphate, this solution was also allowed to stir for a further 5 minutes. A solution of 4-[(2-methylpropan-2-yl)oxy]piperidine hydrochloride (35 mg, 0.178 mmol) in N,N-dimethylacetamide (1 mL) and triethylamine (25 μl, 0.179 mmol) was then added and the reaction left to stir at ambient temperature for 2 hours before being purified by preparative HPLC to afford the desired compound; m/z (LC-MS, ESI+), RT=1.74 (M+H 420.4).
