To a solution of methyl 2-{[(4-fluorophenyl)methyl]oxy}-4-(1-methyl-1H-pyrazol-4-yl)-5-(4-morpholinylmethyl)benzoate (may be prepared as described in Description 18; 144 mg, 0.33 mmol) in tetrahydrofuran (4 ml) was added lithium hydroxide (23.54 mg, 0.98 mmol) and water (1 ml). The mixture was stirred at room temperature for 18 hours then neutralised with 2M hydrochloric acid (0.79 ml, 1.59 mmol). The solvent was removed in vacuo and the residue redissolved in N,N-dimethylformamide (4 ml). Diisopropylethylamine (0.11 m, 0.66 mmol), 4-pyridazinamine (40.5 mg, 0.43 mmol), 1-hydroxy-7-azabenzotriazole (53.5 mg, 0.39 mmol) and EDC (94 mg, 0.49 mmol) were added and the solution was stirred for 3 hours. The solvent was removed in vacuo and the residue purified by MDAP to yield the title compound as a white solid. 57 mg.
