N-(4-Methoxybenzyl)-5-(3-(6-(2-methylpiperidin-1-yl)pyrazin-2-yl)-1-tosyl-1H-indol-5-yl)-1,3,4-oxadiazol-2-amine (177 mg, 0.272 mmol) was weighed into a 5 mL glass microwave tube. The material was dissolved in TFA (1.5 mL) (Aldrich). The tube was sealed and the solution was heated at 120° C. for 10 min in an Initiator microwave reactor (Personal Chemistry, Biotage AB, Inc., Uppsala, Sweden). The excess TFA was removed in vacuo, the crude residue was treated with 1N NaOH and extracted with EtOAc. The organic layer was dried over MgSO4, filtered and concentrated. The material was used in the next step without purification. MS (ESI, pos. ion) m/z 530.0 (M+1).
