Cyclopropanecarbonyl chloride → HCID 67001731, compound

Participants

Reaction Steps

A solution of cyclopropylcarbonyl chloride (0.072 mL, 0.79 mmol) CH2Cl2 (1 mL) was added to an ice-cooled solution of the product of Example 72A (218 mg, 0.716 mmol) in CH2Cl2 (5 mL). The reaction was stirred with ice cooling under nitrogen for 45 minutes and then it was allowed to warm to room temperature for 4 hours. The reaction was quenched by addition of methanol (2 mL) and the solution was stirred for 10 minutes. The reaction mixture was then concentrated under vacuum. The residue was purified by HPLC (30×100 mm, C18, Waters XBridge™ column eluted with 0.1 M aqueous (NH4)2CO3-methanol, 80:20-0:100 over 15 minutes) to provide the title compound: MS (DCI) m/z 373 (M+H)+.
