Reaction Steps

To a solution of 2-amino-6-(trans-2-methylcyclopentyloxy)benzonitrile (Example 264a) (150 mg, 0.694 mmol) in dimethylacetamide (3 mL) under N2 was added sulfamoyl chloride (3 equiv.). The reaction mixture was stirred at room temperature under N2 for 2 hours, diluted with ethyl acetate (50 mL) and quenched with water (20 mL). The layers were separated. The organic extract was evaporated. Ethanol (3 mL) and aqueous NaOH (2N, 2.5 equiv.) were consecutively added to the residue. The resulting mixture was heated at 90° C. for 16 hours. The workup was performed as in Example 111 to provide the desired product (160 mg, 78%) as a white powder. 1H NMR (400 MHz, DMSO-d6) δ 1.02 (d, J=6.4 Hz, 3H), 1.26 (m, 1H), 1.71 (br s, 3H), 1.89 (m, 1H), 2.12 (m, 1H), 2.24 (m, 1H), 4.55 (br s, 1H), 6.60 (d, J=8.0 Hz, 1H), 6.71 (d, J=8.0 Hz, 1H), 7.45 (t, J=8.0 Hz, 1H), 7.73 (br s, 1H), 8.35 (br s, 1H), 10.96 (br s, 1H).
