Reaction Steps

To a dichloromethane solution (32 mL) of tert-butyl (S)-4-(4-fluorophenyl)-5-(pivaloyloxy)-5,6-dihydropyridine-1(2H)-carboxylate (1.62 g, 4.29 mmol) synthesized in Reference Synthesis Example 136, trifluoroacetic acid (6.5 mL) was added and the resultant mixture was stirred at room temperature for 20 hours. After completion of the reaction, saturated sodium bicarbonate aqueous solution was added to the reaction solution and extraction from the resultant mixture with ethyl acetate was performed. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to obtain the title compound as a crude product.
