Procedure
To a solution of the intermediate from step B (4.74 g, 15.84 mmol) in DMF (30 mL) was added hydrazine (1.58 mL, 35% by wt., 17.43 mmol). After stirring the reaction at room temperature for 18 hours, it was concentrated in vacuo. The residue was suspended in ethyl acetate and washed with water (2×) and saturated NaCl solution (2×). The organic layer was dried over anhydrous MgSO4 filtered and concentrated in vacuo. 1H NMR (CDCl3, 500 MHz): 8.02 (s, 1H), 7.69 (d, J=8.2 Hz, 1H), 7.52 (d, J=8.2 Hz, 1H), 7.07 (s, 1H), 1.66 (s, 9H). LC-MS=2.52 min; (M+H−56)=257.1.
