Procedure

reaction on at 1045am 1/1/12

EDCI (0.083, 0.44 mmol) and HOBt (0.005 g, 0.04 mmol) were added to a solution of MNR51-1 (105 mg, 0.36 mmol) in DCM (5 mL) and the mixture was stirred for 20 minutes. Dimethylamine (~5.6 M in absolute ethanol, 0.097 mL, 0.54 mmol) was added and the reaction mixture stirred at room temperature. After 5 hours the reaction looked complete by TLC and it was quenched with sodium bicarbonate (10 mL) and extracted with DCM (3 x 10 mL), dried over MgSO4, filtered and concentrated to give a brown oil (0.075 g)
