Reaction Conditions

Reaction Steps

A mixture of N-(2-chloro-5-fluoropyrimidin-4-yl)octahydroindolizin-7-amine (54 mg, 0.2 mmol), 1-(5-amino-2-cyclopropyl-4-fluorophenyl)-4-methyl-1H-tetrazol-5-one (52 mg, 0.21 mmol; prepared according to US20110130415 pages 43-48, which is hereby incorporated by reference in its entirety) and para-toluenesulfonic acid monohydrate (38 mg, 0.2 mmol) in isopropyl alcohol (3 ml) were combined in a sealed vial, heated to 70° C. and stirred for 2 days. After cooling, the mixture was concentrated under vacuum to leave a crude residue. The residue was purified by preparative high-performance liquid chromatography to give a solid. The solid was partitioned between EtOAc (20 ml) and 1N NaOH (20 ml). The aqueous layer was extracted with EtOAc (2×20 ml) and the combined organic extracts were dried (MgSO4), filtered and the solvent removed in vacuo to leave the product (46 mg, 47%) as a solid after freeze-drying from MeCN/H2O.
