Compound 170: 2-((S)-1-[1,4]Dioxan-2-ylmethoxy)-9-(2-propoxy-ethoxy)-6,7-dihydro-pyrimido[6,1-a]isoquinolin-4-one Intermediate 6 (0.15 g, 0.45 mmol, 1 eq.), 2-Propoxy-ethanol (63 muL, 0.55 mmol, 1.2 eq.) and PPh3 (144 mg, 0.55 mmol, 1.2 eq.) were suspended in 1,4-dioxane (5 mL) and the mixture was degassed with N2. DIAD (0.108 mL, 0.55 mmol, 1.2 eq.) was added and the reaction was stirred at RT overnight. 0.5 eq. of DIAD and PPh3 were added, and the reaction mixture was stirred at room temperature for an extra 2 h. Reaction mixture was diluted with brine, extracted with EtOAc, dried over MgSO4 and concentrated. Crude product was purified on silicagel column to give compound 170.
