(1S,3R)-3-amino-2,2-dimethylcyclobutan-1-ol

Conditions: temp:85.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of (1S,3R)-3-amino-2,2-dimethylcyclobutanol (550 mg crude), 4-chloro-2-(methylthio)pyrimidine-5-carbonitrile (887 mg, 4.78 mmol) and DIEA (1.12 g, 8.7 mmol) in isopropanol (20 mL) was stirred at 85° C. for 3 h. After cooling to room temperature, the reaction mixture was concentrated and the residue was purified by silica gel column chromatography (0.6% MeOH in DCM) to afford the title compound (760 mg, 2.88 mmol, 66.3% yield). MS (ESI) m/z 265.1 [M+1]+. After cooling to room temperature the reaction mixture was concentrated the residue was purified by silica gel column chromatography (0.6% MeOH in DCM)
