Reaction Steps

Example 22 was prepared according to procedures described in Example 2, Step A and Step C, substituting tert-butyl 3-((1-(4-(methylsulfonyl)phenyl)-2-oxo-1,2-dihydropyridin-4-yloxy)methyl)azetidine-1-carboxylate for tert-butyl 4-(1-(4-(methylsulfonyl)phenyl)-2-oxo-1,2-dihydropyridin-4-yloxy)piperidine-1-carboxylate in Step A and 2-chlorophenyl chloroformate for 1,1,1-trifluoropropan-2-yl chloroformate in Step C. 1H NMR (500 MHz, CDCl3) δ 8.09 (d, J=8.25 Hz, 2H), 7.62 (d, J=8.25 Hz, 2H), 7.43 (dd, J=7.97, 1.37 Hz, 1H), 7.32 (d, J=7.70 Hz, 1H), 7.16-7.31 (m, 3H), 6.28 (d, J=2.20 Hz, 1H), 6.25 (dd, J=7.70, 2.75 Hz, 1H), 4.41 (app brs, 1H), 4.31 (app brs, 1H), 4.23 (d, J=6.05 Hz, 2H), 4.20 (app brs, 1H), 4.04 (app brs, 1H) 3.15-3.26 (m, 1H), 3.11 (s, 3H). MS (ESI) 489 (M+H).
