A mixture of (S)-pyrrolidin-3-ylmethanol (0.150 g, 1.5 mmol), CHCl3 (5 mL) and DIEA (0.5 mL, 3 mmol) was treated with a mixture of (3-methyl-4-(methyl(7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)cyclohexyl)methanesulfonyl chloride (0.208 g, 0.41 mmol), CHCl3 (3.0 mL), and DMF (1.5 mL). After 1 h, the mixture was concentrated and the resulting residue was chromatographed using 0→8% MeOH in CH2Cl2. The product fractions were pooled and concentrated to give ((3S)-1-((3-methyl-4-(methyl(7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)cyclohexyl)methylsulfonyl)pyrrolidin-3-yl)methanol (0.126 g (54%). MS for C27H37N5O5S2 (ESI) (MH)+ m/z=576.
