反応手順

Cyclopropyl-2,5-dimethyl-1H-imidazole-4-carboxylic acid ethyl ester (0.7 g, 3 mmol) was dissolved in 20 mL dry THF and cooled to 0° C. Lithium aluminum hydride (3.4 mL, 1M in THF, 3 mmol) was added dropwise and stirred for 1 h at 0° C. The reaction mixture was quenched with 0.13 ml of water, 0.13 ml of 4N sodium hydroxide and 0.4 ml of water. Sodium sulfate was added, stirred for 10 min, filtered and evaporated to dryness to obtain the desired compound as a light yellow solid (0.52 g, 93%), MS: m/e=167.4 (M+H)+.
