実験手順

tert-butyl {[4-(4-chloro-2-{1-[1-(diphenylmethyl)azetidin-3-yl]-1H-pyrazol-5-yl}phenoxy)-3-cyanophenyl]sulfonyl}1,3-thiazol-4-ylcarbamate, (Preparation 680, 224 mg, 0.287 mmol) was dissolved in dichloromethane (10 ml) and N,N,N′,N′-tetramethylnaphthalene-1,8-diamine (150 mg, 0.70 mmol) was added, followed by 1-chloroethyl chloroformate (0.07 ml, 0.65 mmol) and the solution was stirred at room temperature for 3.5 hours. Concentrated in vacuo and the residue was dissolved in methanol (10 ml) and refluxed for 4 hours. Concentrated in vacuo to give the crude title compound as a brown gum, 200 mg. This material was used without purification in Example 815.
