Participants

Reaction Steps

A solution of 0.13 g (0.33 mmol) of (7S,8aS)-7-(4-((methoxycarbonyl)methyl)phenoxy)methyl-2-(5-fluoropyrimidin-2-yl)-1,2,3,4,6,7,8,8a-octahydro-pyrrolo[1,2-a]pyrazine (Example 11i) in 15 mL of anhydrous ethyl ether was added dropwise to an ice-cold suspension of 0.025 g (0.65 mmol) of lithium aluminum hydride in 15 mL of anhdrous ethyl ether and the mixture stirred for 30 minutes. The reaction was carefully quenched at 0° C. with 0.025 mL of water, 0.025 mL of 15% sodium hydroxide, and 0.075 mL of water. The precipiate which formed was filtered through Celite, the filtrate concentrated in vacuo, and purification of the residue by flash silica gel chromatography with 95:5 ethyl acetate:methanol gave 0.075 g (63%) of the title compound. Mp (.HCl) 145-147° C. HRMS calc'd for C20H26FN4O2 (MH+): 373.2040, found: 373.2054.
