[(2R)-piperazin-2-yl]methanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Dissolve 1-chloro-4-(4-fluorophenyl)phthalazine (0.1 g, 0.39 mmol), (R)-piperazin-2-ylmethanol (0.07 g, 0.58 mmol) and diisopropylethylamine (0.34 mL, 1.93 mmol) in DMSO (1 mL). Stir the reaction at 120° C. for 64 h. Purify the reaction mixture by flash silica gel chromatography (0-10% 2 M ammonia/MeOH in CH2Cl2) to yield the title compound as a brown solid (0.11 g, 84%). ES/MS m/z 339.0 (M+1). the reaction at 120° C. for 64 h Purify the reaction mixture by flash silica gel chromatography (0-10% 2 M ammonia/MeOH in CH2Cl2)
