Formaldehyde → HCID 60077775, compound

Participants

Reaction Steps

Formaldehyde (37% wt. % solution in H2O, 0.5 mL) was added to a solution of 4-[4-(2(S)-tert-Butoxycarbonylamino-3,3-dimethylbutyryl)-phenyl]-piperazine-1-carboxylic acid benzyl ester in methanol (3 mL) and ethyl acetate (1 mL). The mixture was degassed and 10% palladium on charcoal (20 mg) was added. Hydrogen gas was bubbled through the suspension for 15 minutes when a balloon containing hydrogen was introduced to the reaction. After 18 hours, the catalyst was removed by filtration and the solvents were removed in vacuo to give a yellow oil which was used without further purification (0.15 g, 100% crude).
