Procedure
A 31-mg aliquot of crude product from Step 2 was dissolved in CH2Cl2 (3 mL) and 4 M HCl in dioxane (1 mL) was added. The mixture was stirred at rt for 2 h and concentrated to leave (R)-4-(pyridin-4-yl)-2-(pyrrolidin-2-yl)thiazole as its HCl salt (35 mg). LC-MS Method 1 tR=0.40 min, m/z=232.
