To a solution of 4-(3-amino-benzyl)-5,6,7,8-tetrahydro-2H-phthalazin-1-one (4) (50 mg, 0.195 mmol) in dry DCM (10 ml) was added 2-isocyanato-2-methyl-propionic acid methyl ester (60 mg, 0.428 mmol). The resulting solution was stirred for 2 days, washed with water (3×10 ml), dried over sodium sulphate and concentrated in vacuo to yield a semi-crystalline solid (44 mg).
