実験手順

The racemic form of the title compound was obtained using 4-(4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl)thiophene-2-carboxamide obtained in Step A of Example 148 and 1-methoxybutan-2-yl 4-methylbenzenesulfonate, in the same manner as in Step B of Example 148 and Step C of Example 148. The obtained racemic form was resolved by HPLC (column: L-column2 ODS (trade name) 20 mmID×150 mmL, 5 μm, manufactured by Daicel Chemical Industries, mobile phase: water/acetonitrile (containing 10 mM ammonium carbonate)) to give the title compound having a shorter retention time.
