反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: The title compound was prepared according to general procedure AA using 5-({[(4-Methoxy-2,6-dimethylphenyl)sulfonyl](methyl)amino}methyl)furan-3-carboxylic acid (75 mg, 0.21 mmol), CDI (41 mg, 0.25 mmol) and 1-[4-(pyrrolidin-1-ylmethyl)phenyl]methanamine (37 mg, 0.21 mmol) in THF (4.5 mL) and DMF (0.6 mL). A portion of the crude product was purified using prep method A. A portion of the crude product was purified

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a stirred solution of 5-({[(4-bromo-2,6-dichlorophenyl)sulfonyl](methyl)amino}methyl)furan-3-carboxylic acid (40 mg, 0.09 mmol), EDCI (23 mg, 0.12 mmol) and HOBt (15 mg, 0.11 mmol) in DMF (3 mL) was added 1-[4-(pyrrolidin-1-ylmethyl)phenyl]methanamine (17 mg, 0.09 mmol). The reaction was stirred at ambient temperature for 3 days, then absorbed on to an Isolute SCX-2 cartridge, washing with MeOH and eluting the product with 7M NH3 in MeOH. The filtrate was concentrated in vacuo and a portion of the crude product purified using prep method C. absorbed on to an Isolute SCX-2 cartridge washing with MeOH eluting the product with 7M NH3 in MeOH The filtrate was concentrated in vacuo a portion of the crude product purified

反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Dissolve 4-(pyrrolidin-1-ylmethyl)-benzonitrile (918 mg, 4.93 mmol) in methanol (32 mL). Add cobalt(II) chloride hexahydrate (2.7 g, 9.87 mmol) and stir for 20 min. Cool the mixture to 0° C., and carefully add sodium borohydride (1.86 g, 49.3 mmol) in small batches. Stir the mixture for 1.5 h at room temperature. Quench the mixture with water and partition between water and chloroform. Extract the aqueous phase three times with chloroform/iso-propanol (3:1). Dry the combined organic extracts over MgSO4, filter, and concentrate in vacuo. Purify by chromatography on silica gel (80 g) eluting with a gradient of DCM/(chloroform:methanol:concentrated NH4OH 80:18:2) (1:0 over 5 min, 19:1 over 5 min, 9:1 over 5 min, 85:15; 50 mL/min) to give the title compound (421 mg, 45%). MS (ES+) m/z: 191 (M+H)+, Quench the mixture with water partition between water and chloroform Extract the aqueous phase three times with chloroform/iso-propanol (3:1) Dry the combined organic extracts over MgSO4 filter concentrate in vacuo Purify by chromatography on silica gel (80 g) eluting with a gradient of DCM/(chloroform:methanol:concentrated NH4OH 80:18:2) (1:0 over 5 min, 19:1 over 5 min, 9:1 over 5 min, 85:15; 50 mL/min)
