実験手順
1-(Benzo[d][1,3]dioxol-5-yl)-N-(5-((2-chlorophenyl)((R)-3-hydroxypyrrolidin-1-yl)methyl)thiazol-2-yl)cyclopropanecarboxamide (3.00 g, 6.02 mmol) was suspended in 200 mL of anhydrous dichloromethane containing N,N-dimethylpyridin-4-amine (2.20 g, 18.0 mmol). (1S,2R,5S)-2-Isopropyl-5-methylcyclohexyl chloroformate (1.91 mL, 9.00 mmol) was slowly added to the suspension and the resulting mixture was heated to reflux for 16 hours. The resulting pale yellow solution was allowed to cool to room temperature, diluted with 20 mL of methanol, and then evaporated to dryness. The crude reaction mixture was separated on 330 g of silica gel utilizing a gradient of 0-5% methanol in dichloromethane to yield the pure product as a pale yellow solid (2.0087 g, 2.9529 mmol, 49.1%). ESI-MS m/z calc. 679.3, found; 680.5 (M+1)+; Retention time 3.88 minutes.
