Reaction Steps
To a solution of 2,4-dichloro-7-(4-fluorophenyl)-5,7-dihydrofuro[3,4-d]pyrimidine (Preparation M) (150 mg, 0.526 mmol) in THF (2631 μL) was added (R)-1-cyclopropylethanamine, HCl (128 mg, 1.052 mmol) and DIEA (368 μL, 2.105 mmol). The mixture was heated at 40° C. for 2 h and stirred at RT overnight. The mixture was concentrated and purified by column chromatography on silica gel to give 2-chloro-N—((R)-1-cyclopropylethyl)-7-(4-fluorophenyl)-5,7-dihydrofuro[3,4-d]pyrimidin-4-amine (Preparation Mf) (25 mg, 0.075 mmol, 14.24% yield) as a mixture of 2 diasteriomers. LC-MS (M+H)+=334.1.
