Reaction Steps

NaHMDS solution (1M in THF, 7.13 mL, 7.13 mmol) was added slowly to a mixture of 7-((4-chlorothiazol-2-yl) (hydroxy)methyl)-5-(3-fluorophenyl)-1,3-dimethyl-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione (Example 27, step 1) (1 g, 2.376 mmol), dimethyl malonate (0.819 mL, 7.13 mmol) and boron trifluoride THF complex (0.236 mL, 2.139 mmol) in THF (30 mL).
