Participants

Reaction Steps

Following the procedure as described in Example 1 and making variations as required to replace 2-cyclopropylethanol with adamantan-1-ylmethanol and 2,4,5-trifluoro-N-(methylsulfonyl)benzamide with 5-chloro-2,4-difluoro-N-(methylsulfonyl)benzamide (WO 2012007883 A1), the title compound was obtained as a colorless solid (0.20 g, 8%): 1H NMR (300 MHz, DMSO-d6) δ 12.10 (s, 1H), 7.77 (d, J=7.5 Hz, 1H), 7.23 (d, J=12.5 Hz, 1H), 3.72 (s, 2H), 3.35 (s, 3H), 1.99 (br s, 3H), 1.75-1.64 (m, 12H); 13C NMR (75 MHz, DMSO-d6) δ 162.3 (d, J=2.0 Hz), 159.8 (d, JC-F=255 Hz), 158.3 (d, JC-F=11 Hz), 130.6 (d, JC-F=4 Hz), 116.8 (d, JC-F=3 Hz), 113.6 (d, JC-F=14 Hz), 102.7 (d, JC-F=28 Hz), 79.1, 41.2, 38.5, 36.4, 33.4, 27.3; MS (ES+) m/z 415.6, 417.6 (M+1).
