実験手順

A solution of 4-benzyloxycarbonyl-1-{methyl[1-(4-pyridyl)-4-piperidinyl]amino}-2-piperazinone (2.22 g) and a 4N solution of hydrochloric acid in ethyl acetate (2.6 ml) in methanol (50 ml) was combined with 10% Pd/C (50% hydrated, 0.44 g) and stirred at room temperature for 5 hours under a hydrogen atmosphere. The catalyst was filtered off and the reaction mixture was concentrated to obtain the title compound. (2.13 g) as a yellow amorphous material.

後処理

  1. filtrationThe catalyst was filtered off
