Procedure
Lithium hydroxide, monohydrate (1.11 g, 26.4 mmol) was added to a solution ethyl 3-(3-((((3aR,4R,6R,6aS)-6-(4-((2,4-dimethoxybenzyl)amino)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)methyl)(isobutyl)amino)cyclobutyl)propanoate (1.75 g, 2.64 mmol) in Tetrahydrofuran (13 ml, 160 mmol) and Methanol (3 ml, 70 mmol). The reaction was stirred for 24 hours at RT, acidified with 1 N HCl to pH=6, the volatiles removed in vacuo and remaining water removed by azeotropic distillation with ethanol followed by 18 hours on lyophilizer. The resulting off white solid was used without further purification.
