Participants

Conditions

Temperature: 25 °C

Procedure

To a solution of the mixture from Step 1 in absolute MeOH (5 mL) was added Pd/C (10% Pd, 100 mg). The mixture was stirred at 25° C. for 1 hour under H2 atmosphere. The solids were filtered off and the filtrate was concentrated to give the product (60 mg, two-step yield 66%).
