Participants

Reaction Steps

To a solution of 360 (150 mg, 0.329 mmol) in MeOH (10 mL) was added ammonium chloride (35.3 mg, 2 eq, 0.660 mmol) in water (1 mL) and zinc powder (86 mg, 4 eq, 1.320 mmol) and the reaction mixture was heated to reflux for 3 hours. The mixture was cooled to RT then filtered and the filtrate was concentrated under reduced pressure. The residue was dissolved in DCM and washed with water. The organic phase was collected, dried over anhydrous Na2SO4, filtered and concentrated to afford the title compound 361 (98 mg, 70% yield) that was used in the next step with no additional purification. MS (m/z): 425.5 (M+H)
