Procedure

A mixture of 4-(7-fluoro-quinazolin-4-yl)-piperidin-1-carboxylic acid tert-butyl ester (31.6 mg, 95.5 μmol), as prepared in Example 12b, 3-[1,2,4]-triazol-4-yl-propan-1-ol (ChemPacific) (12.0 mg, 94.5 μmol), and KOtBu (11.7 mg, 104 μmol) in DME (100 μL) and DMSO (50 μL) was stirred at rt for 1 hr. The resulting homogeneous amber solution was partitioned with DCM (2 mL) and 0.5M sodium phosphate/pH 7 (2 mL). The organic layer was concentrated to provide the crude title compound. LC/MS (ESI): calcd mass 438.2, found 439.1 (MH)+.
