Acetic Acid → 5-(4-methyl-1,3-thiazol-2-yl)-1-(3-{(1S,5R)-1-[4-(trifluoromethyl)phenyl]-3-azabicyclo[3.1.0]hex-3-yl}propyl)-2,4(1H,3H)-pyrimidinedione

Participants

Reaction Steps

3-[5-(4-methyl-1,3-thiazol-2-yl)-2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl]propanal (Prep.45, 0.109 mmol) was suspended in 1,2-Dichloroethane (DCE) (1 ml) and Acetonitrile (1 ml). Acetic acid (9.36 μl, 0.164 mmol) followed by (1S,5R)-1-[4-(trifluoromethyl)phenyl]-3-azabicyclo[3.1.0]hexane (P4 24.77 mg, 0.109 mmol) were added and the mixture was stirred at rt for 20 minutes. Then the resulting solution was cooled to 0° C. and SODIUM TRIACETOXYBOROHYDRIDE (25.4 mg, 0.120 mmol) was added. The mixture was allowed to reach r.t. under stirring and left at rt overnight. The mixture was treated with NaHCO3 aqueous saturated solution (5 mL) and extracted with EtOAc (3×5 mL). The organic was dried (Na2SO4 and rotary) to afford a yellow solid that was submitted to LC preparative purification. Fractions were collected, dried under vacuum to afford the title compound as a white solid (6.8 mg, 12%).
