実験手順

The methods described in Example 586 were used to hydrogenate 1-[4-amino-2-(2-methoxyethyl)-2H-pyrazolo[3,4-c]quinolin-1-yl]-2-methylpropan-2-ol (1.75 g, 5.5 mmol) in the presence of platinum (IV) oxide (1.5 g) and trifluoroacetic acid (20 mL) and purify the product with the modification that before recrystallization, the product was also triturated with acetonitrile. 1-[4-Amino-2-(2-methoxyethyl)-6,7,8,9-tetrahydro-2H-pyrazolo[3,4-c]quinolin-1-yl]-2-methylpropan-2-ol (1.0 g) was obtained as white crystals, mp 163-165° C.

後処理

  1. custompurify the product with the modification
  2. customthat before recrystallization
  3. customthe product was also triturated with acetonitrile
