Procedure
Methylmagnesium bromide (0.769 mL, 0.77 mmol) was added at 0° C. to a solution of ethyl 2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenylamino)-7,8-dihydro-5H-pyrano[4,3-d]pyrimidine-4-carboxylate (150 mg, 0.37 mmol) in dry THF (5 mL). 4 eq extra equivalents of methylmagnesium bromide were added over 2 h. The crude product was partitioned between DCM and water. The organic phase was separated and the solvent was evaporated. The crude product was purification on a prepHPLC affording 2-(2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenylamino)-7,8-dihydro-5H-pyrano[4,3-d]pyrimidin-4-yl)propan-2-ol (11.00 mg, 7.59%).
