Reaction Steps

To a solution of 44 (610 mg, 1.28 mmol) and THF (5 mL) was added MeOH (1 mL) followed by the dropwise addition of 1M NaOH (5105 μL, 5.11 mmol). The reaction was stirred for 1 h, cooled to 0° C. and acidified to pH 3 with 1N HCl. The mixture was extracted twice with 10% MeOH in DCM (25 mL). The organic layers were combined and concentrated to afford 270 mg (45.6%) of 2-(4-chloro-3-fluorophenyl)-2-(2-(tetrahydro-2H-pyran-4-ylamino)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine-7-carboxamido)acetic acid (46) which was used without further purification.
