Procedure

To a solution of 2-(4-(3,4-dichlorobenzyl)-2-morpholinothiazol-5-yl)acetonitrile (87.0 mg, 0.236 mmol) in DMF (0.74 mL) was added sodium azide (21.6 mg, 0.332 mmol) and NH4Cl (17.8 mg, 9.53 mmol) and the resulting mixture was heated to 140 degrees overnight. More sodium azide (43 mg, 0.66 mmol) and NH4Cl (36 mg, 19 mmol) were added and the reaction was heated to 120 degrees overnight. The reaction was cooled and taken up in ethyl acetate (25 mL) and water (5 ml). The layers were separated and the organic layer was washed with water (3×5 mL).). The organic layer was dried and concentrated in vacuo. The residue was purified by preparative reverse phase chromatography to give 5 mg (5% yield) of the title compound. as a white solid.
