Reaction Conditions:

with potassium carbonate in dimethyl sulfoxide at 100; for 16 h;

Steps:

34.1 Step 1

To a stirred solution of compound 2 ’-Fluoro acetophenone (30 g, 0.22 mol, 1 eq) and piperidine (19.6 g, 0.23 mol, 1.05 eq) in DMSO (200 mL) was added K2CO3 (45.5 g, 0.33 mol, 1.5 eq). The reaction was stirred at 100 °C for 16 h. TLC showed the reaction was completed. The mixture was cooled to room temperature and poured into water (1 L), extracted with ethyl acetate (400 mL*4). The combined organic layers were washed with brine (300 mLX3), dried with Na2SO4, filtered and concentrated in vacuum to give compound 34A (42 g, Y=94.2%) as a yellow oil, which was used directly for the next step without further purification.
