Participants

Conditions

Temperature: 110 °C

Procedure

5-(Benzylthio)-7-chloro[1,3]thiazolo[4,5-d]pyrimidin-2-amine (6.0 g, 19.4 mmol) was dissolved in NMP (30 mL). DIPEA (8.4 mL, 48.5 mmol) and 2-amino-(2R)-1-pentanol (3.5 g, 33.9 mmol) were added and the mixture was heated to 110° C. for 4 days. After cooling to room temperature, the mixture was poured into water (200 mL). The precipitated product was collected by filtration, washed with water and used in the next step without further purification (7.0 g, 97% yield).
