Procedure:
421 mg (1.64 mmol) of 2-(tert-butoxycarbonylamino)-4,4,4-trifluorobutanoic acid were suspended in a mixture of N,N-dimethylformamide (5 mL) and dichloromethane (5 mL) and HATU (624 mg, 1.64 mmol) and DIEA (286 μl, 1.64 mmol) were added. The resulting suspension was stirred at room temperature for 2 hours and then 1-amino-N-phenyl-1H-pyrrole-2-carboxamide (300 mg, 1.49 mmol) was added. The resulting solution was stirred at room temperature overnight and the dichloromethane was removed in vacuum. 25 mL of water were added to the remaining solution and, after vigorous stirring, the solid that formed was filtered and washed with water. 582 mg (89% yield) of the title compound were obtained as a white solid.

Procedure:
A suspension of 3.60 g (0.02 mole) of theophylline and 1.38 g (0.01 mole) of K2CO3 in 75 ml of acetone was refluxed overnight and then allowed to react at reflux with 3.00 g (0.02 mole) of pivaloxymethyl chloride for 2 days. The suspension was filtered and the residue was washed with acetone (200 ml). The combined filtrate and wash was concentrated in vacuo and the residue was extracted with boiling heptane (200 ml). The heptane solution was cooled in the refrigerator for 0.5 hr then filtered. The residue was dried in vacuo to give 1.50 g (mp 108°-109.5°) of 7-pivaloxymethyl theophylline.
