Reaction Steps

cis-2-{[1-Benzyl-7-({[(1-methyl-1H-imidazol-4-yl)sulfonyl]amino}methyl)-1,2,3,4-tetrahydronaphthalen-2-yl]carbamoyl}cyclopropanecarboxylic acid (382 mg, 0.731 mmol) was dissolved in tetrahydrofuran (10 mL) and acetyl chloride (5 mL, 88 mmol) was added. The reaction mixture was heated under reflux for 2 h. The reaction mixture was diluted with water and extracted with dichloromethane. The combined organic extracts were washed with aqueous sodium bicarbonate solution, dried (sodium sulfate) and concentrated in vacuo. The crude product was used for the next step without further purificiation. Yield: 377 mg (light orange oil).
