Participants

Reaction Steps

Following the procedure as described in Example 9, making variations only as required to use (3-bromopropoxy)(tert-butyl)dimethylsilane in place of 2-cyclopropylethyl 4-methylbenzenesulfonate to react with N-(3-fluorobenzyl)-5-(4-hydroxy-2-oxopyridin-1(2H)-yl)-3-methylthiophene-2-carboxamide, the title compound was obtained as a yellowish viscous oil in quantitative yield: 1H NMR (300 MHz, CDCl3) δ 7.54 (d, J=7.8 Hz, 1H), 7.35-7.27 (m, 1H), 7.12 (d, J=7.8 Hz, 1H), 7.05 (d, J=9.6 Hz, 1H), 7.00-6.94 (m, 1H), 6.85 (s, 1H), 6.19 (t, J=5.8 Hz, 1H), 6.07 (dd, J=7.8, 2.7 Hz, 1H), 5.98 (d, J=2.7 Hz, 1H), 4.59 (d, J=5.8 Hz, 2H), 4.07 (t, J=6.0 Hz, 2H), 3.77 (t, J=6.0 Hz, 2H), 3.52 (t, J=6.0 Hz, 2H), 2.54 (s, 3H), 0.88 (s, 9H), 0.04 (s, 6H); MS (ES+) m/z 531.5 (M+1).
