YieldReaction ConditionsOperation in experiment
With thionyl chloride; In toluene; at 80℃; for 0.25h; The compound was prepared according to the procedure for Intermediate 3, starting from Intermediate 2 and 1-cyanocyclopropanecarbonyl chloride (generated in situ from 1- cyanocyclopropanecarboxylic acid and excess thionyl chloride in toluene at 800C for 15 min.). APCI-MS m/z: 576 [MH+].
With oxalyl dichloride;N,N-dimethyl-formamide; In dichloromethane; Compound 1-238[00461] To a solution of l-cyanocyclopropanecarboxylic acid (10 equiv) in dichloromethane was added oxalyl chloride (9 equiv) and catalytic N,iV-dimethylformamide. Once gas evolution ceased, this crude reaction mixture was added portion- wise to a suspension of Compound 1-107 (1 equiv) in dichloromethane/pyridine (1 :1) until complete consumption of starting material was observed by LS/MS. Purification via washing residual solid with diethyl ether following an aqueous ammonium chloride and dichloromethane workup (and subsequent concentration of organics) provided the desired compound as a yellow solid (27percent).1H NMR (400 MHz, DMSO-i/6) 9.41 (s, IH), 9.09 (d, IH), 8.04 (s, IH), 7.53 (s, IH), 7.41- 7.30 (m, IH), 7.24 (d, IH), 7.24-7.20 (m, IH), 7.11 (t, IH), 7.03 (bs, IH), 6.86 (t, IH), 5.90 (s, 2H), 1.72-1.64 (m, 4H) ppm.
With oxalyl dichloride; N,N-dimethyl-formamide; In dichloromethane; at 0℃; for 2h; [00248] To a solution of 1-cyanocyclopropanecarboxylic acid (80 mg, 0.72 mmol) and oxalyl dichloride (136 mg, 1.08 mmol) in DCM (5 mL) was added a drop of DMF at 0 °C, then the mixture was stirred for 2 h, after completion the reaction mixture solution was used for next step directly.
