Procedure
Reactions were performed in the same manner as in Example 1, (J) by using (3S)-1-[8-({[4-(tert-butyl)-1,3-thiazol-2-yl]amino}carbonyl)-3-formyl-4-oxo-4H-pyrido-[1,2-a]pyrimidin-2-yl]hexahydro-3-pyridinyl formate (524 mg, 1.083 mmol), and the resulting residue was purified by silica gel column chromatography (chloroform→chloroform:methanol=100:1→70:1→50:1) to obtain 742 mg (100% or more) of the title compound as a brown oily substance in a mixture containing byproducts.
Workup
- customthe resulting residue was purified by silica gel column chromatography (chloroform→chloroform:methanol=100:1→70:1→50:1)
