実験手順

To a solution of 5-[(5S*,9R*)-9-(4-Cyanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.4]non-7-ylmethyl]-thiophene-3-carboxylic acid (example 37) (0.150 g, 0.27 mmol) in DCM/MeOH (5:1 mL) was added trimethylsilyldiazomethane (2.0 M solution in hexane, 0.33 mL, 0.67 mmol) over a period of three minutes at RT. The reaction mixture was stirred at RT for twenty minutes, quenched by the slow addition of acetic acid (approximatly ten drops) and partitioned between DCM (20 mL) and saturated aqueous sodium bicarbonate (15 mL). The DCM layer was washed with brine (20 mL), dried over sodium sulfate and concentrated to yield a thick oil. LC retention time=3.34 min. Column used: YMC S5 combiscreen ODS 4.6×50 mm (4 min. gradient); Solvent A=10% MeOH, 90% H2O and 0.2% H3PO4; solvent B=90% MeOH, 10% H2O, 0.2% H3PO4.
