Participants

Reaction Steps

Acetone (0.0195 mL, 0.266 mmol) was added to a solution of 2-(4-chlorophenyl)-2-(6-((R)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)-1H-indol-3-yl)ethanamine (107 mg, 0.266 mmol) and N,N-diisopropylethylamine (0.139 mL, 0.797 mmol) in methylene chloride (2.0 mL). The reaction mixture was stirred for 10 minutes, and then sodium triacetoxyborohydride (0.0188 g, 0.0885 mmol) was added. After stirring for 2.5 hours, saturated NaHCO3 was added, and the mixture was stirred vigorously 10 minutes. The mixture was extracted with DCM (3×10 mL). The combined organic were dried (Na2SO4), filtered and concentrated. The crude product was purified by SFC chiral chromatography (Chiral OJH (21.2×250 mm) 25% methanol+0.1% TEA) to give N-((R)-2-(4-chlorophenyl)-2-(6-((R)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)-1H-indol-3-yl)ethyl)propan-2-amine (19.8 mg, 16.8%) as the first peak.
