反応手順

To a solution of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid ethyl ester (0.40 g, 1.3 mmol) (as prepared in the previous step) in ethanol (3 mL) was added a solution of 6M KOH (0.20 mL) and the reaction was stirred for 10 min and then concentrated to give 0.40 g (100%) of the title compound as a yellow solid. 1H-NMR (400 MHz, CD3OD): δ 7.98 (s, 1H), 5.92 (s, 2H), 3.62 (m, 2H), 0.94 (m, 2H), 0.00 (s, 9H). Mass spectrum (ESI-neg, m/z) Calcd. for C11H17N3O3Si, 266.1 (M−H), found 266.0.
