Procedure

In the same manner as in Example 81, 146 mg of the title compound was prepared from 160 mg of sodium (1R,5S,6S)-6-((1R)-1-hydroxyethyl)-2-[[(Z)-2-(4-hydroxymethylthiazol-5-yl)ethen-1-yl]thio]-1-methyl-1-carbapen-2-em-3-carboxylate prepared in Example 41 and 0.047 ml of bromomethyl acetate. NMR (CDCl3) δ: 1.21 (3H, d, J=7.3 Hz), 1.35 (3H, d, J=6.3 Hz), 1.83 (1H, d, J=4.8 Hz), 2.14 (3H, s), 2.50 (1H, t, J=5.9 Hz), 3.29 (1H, dd, J1=6.8 Hz, J2=2.8 Hz), 3.51-3.61 (1H, m), 4.22-4.31 (2H, m), 4.86 (2H, d, J=5.9 Hz), 5.89 (1H, d, J=5.6 Hz), 5.97 (1H, d, J=5.6 Hz), 6.52 (1H, d, J=10.5 Hz), 7.13 (1H, d, J=10.5 Hz), 8.79 (1H, s)
