To a mixture of 1H-pyrrole-3-carboxylic acid (1.40 g, 12.60 mmol), tert-butyl 5-(aminomethyl)-4,6-dimethylpyridin-2-ylcarbamate (3.48 g, 13.86 mmol) and DIPEA (6.60 ml, 37.8 mmol) in DCM (100 ml) was added HBTU (5.73 g, 15.12 mmol) at rt and was stirred at rt for 12 hours. The suspension was filtered off. The solid was washed with DCM and dried under reduced pressure to afford pure tert-butyl 5-((1H-pyrrole-3-carboxamido)methyl)-4,6-dimethylpyridin-2-ylcarbamate. HPLC (Method G) Rt=1.35 min; MS [M+H]+=345.2.
