Procedure

The chloro compound of Step 9 (110 mg, 0.24 mmol), NI-methyl-ethylamine (79 mg, 1.2 mmol), N-ethyldiisopropylamine (210 μL, 1.20 mmol) and caesium fluoride (37 mg, 0.24 mmol) were dissolved in dimethyl sulphoxide (1 mL) and the reaction mixture heated to 110° C. for 5 hours in a ReactiVial™. The reaction mixture was partitioned between ethyl acetate (10 mL) and water (10 mL) and the organic phase separated and washed with water (2×10 mL). The organic phase was then dried over magnesium sulphate and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with dichloromethane:methanol 99:1 to 97:3. The purified material was evaporated and dried to yield a pale yellow solid (66 mg). The PXRD pattern for the solid is shown as FIG. 14.
