To a mixture of 2-cyclopropylethanol (3.45 g) in DME (20 mL) was added sodium tert-butoxide (3.86 g) gradually. The reaction was stirred under nitrogen for 30 mins, then 2-chloro-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (2.54 g) and DME (20 mL) were added. The reaction was heated to reflux (110° C.) overnight, then for another 8 h. The reaction was quenched into water (100 mL) and extracted with EtOAc (2×100 mL). The organics were combined and washed with brine (100 mL) and dried using a hydrophobic frit. The resultant oil was azeotroped with toluene (×2) to give a gum. This was triturated with Et2O (cooled CO2/acetone bath) until the title compound was obtained as a yellow powder (1.579 g) which was placed under high vacuum for 24 h.
