The product of Step 2 (95 mg, 0.184 mmol) was taken up in MeOH (2.0 ml) in a microwave vial, and sodium hydroxide (1.0 M in H2O, 0.369 ml, 0.369 mmol) was added. The reaction was heated to 100° C. for 10 min in the microwave. The colorless solution was adjusted to a pH of 3-4 with 1 N HCl, diluted with water, and extracted with 15% IPA/CHCl3 (2×). The combined organic layers were dried (MgSO4), filtered and evaporated to afford the title compound (85 mg, 0.169 mmol, 92% yield) as an off-white foam.
