Procedure

To a solution of Step 7 intermediate (900 mg, 3.57 mmol) and sulphamic acid (693 mg, 7.142 mmol) in acetone (17.8 ml) was added sodium chlorite (484 mg, 5.357 mmol) in water (5.35 ml) and reaction mixture was stirred for 2 h. The solvent was evaporated, diluted with water and acidified with 1N HCl. Solid obtained was filtered and dried to give 375 mg of title compound as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 2.30 (s, 3H), 3.20 (s, 3H), 3.42 (s, 3H), 3.80 (s, 2H), 12.19 (br s, 1H); MS (m/z) 249.10 (M+H)+.
