Procedure

2-(7-Aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) (1.9 g, 5 mmol) and diisopropyl ethyl amine (DIEA) (2.7 mL) was added to a suspension of 4-(tert-butoxycarbonyl)thiomorpholine-2-carboxylic acid (1.3 g, 5 mmol) in DMF (10 mL) and was stirred at room temperature for 15 minutes. Methyl 5-amino-1H-indazole-3-carboxylate (0.95 g, 5 mmol)) was added to the reaction and was stirred at room temperature for an additional 30 minutes. The reaction was quenched with water (50 mL) and extracted with ethyl acetate (3×20 mL). The extracts were combined, dried using anhydrous sodium sulfate, filtered, and concentrated in vacuo. The crude product (2.1 g) was progressed to the next step without purification.
